[SPARK-17993][SQL] Fix Parquet log output redirection
(Link to Jira issue: https://issues.apache.org/jira/browse/SPARK-17993)
## What changes were proposed in this pull request?
PR #14690 broke parquet log output redirection for converted partitioned
Hive tables. For example, when querying parquet files written by Parquet-mr
1.6.0 Spark prints a torrent of (harmless) warning messages from the Parquet
reader:
```

```
This only happens during execution, not planning, and it doesn't matter
what log level the `SparkContext` is set to. That's because Parquet (versions <
1.9) doesn't use slf4j for logging. Note, you can tell that log redirection is
not working here because the log message format does not conform to the default
Spark log message format.
This is a regression I noted as something we needed to fix as a follow up.
It appears that the problem arose because we removed the call to
`inferSchema` during Hive table conversion. That call is what triggered the
output redirection.
## How was this patch tested?
I tested this manually in four ways:
1. Executing `spark.sqlContext.range(10).selectExpr("id as
a").write.mode("overwrite").parquet("test")`.
2. Executing `spark.read.format("parquet").load(legacyParquetFile).show`
for a Parquet file `legacyParquetFile` written using Parquet-mr 1.6.0.
3. Executing `select * from legacy_parquet_table limit 1` for some
unpartitioned Parquet-based Hive table written using Parquet-mr 1.6.0.
4. Executing `select * from legacy_partitioned_parquet_table where
partcol=x limit 1` for some partitioned Parquet-based Hive table written using
Parquet-mr 1.6.0.
I ran each test with a new instance of `spark-shell` or `spark-sql`.
Incidentally, I found that test case 3 was not a regressionâredirection
was not occurring in the master codebase prior to #14690.
I spent some time working on a unit test, but based on my experience
working on this ticket I feel that automated testing here is far from feasible.

[SPARK-17990][SPARK-18302][SQL] correct several partition related
behaviours of ExternalCatalog
## What changes were proposed in this pull request?
This PR corrects several partition related behaviors of `ExternalCatalog`:
1. default partition location should not always lower case the partition
column names in path string(fix `HiveExternalCatalog`)
2. rename partition should not always lower case the partition column names
in updated partition path string(fix `HiveExternalCatalog`)
3. rename partition should update the partition location only for managed
table(fix `InMemoryCatalog`)
4. create partition with existing directory should be fine(fix
`InMemoryCatalog`)
5. create partition with non-existing directory should create that
directory(fix `InMemoryCatalog`)
6. drop partition from external table should not delete the directory(fix
`InMemoryCatalog`)

[SPARK-18185] Fix all forms of INSERT / OVERWRITE TABLE for Datasource
tables
## What changes were proposed in this pull request?
As of current 2.1, INSERT OVERWRITE with dynamic partitions against a
Datasource table will overwrite the entire table instead of only the partitions
matching the static keys, as in Hive. It also doesn't respect custom partition
locations.
This PR adds support for all these operations to Datasource tables managed
by the Hive metastore. It is implemented as follows
- During planning time, the full set of partitions affected by an INSERT or
OVERWRITE command is read from the Hive metastore.
- The planner identifies any partitions with custom locations and includes
this in the write task metadata.
- FileFormatWriter tasks refer to this custom locations map when
determining where to write for dynamic partition output.
- When the write job finishes, the set of written partitions is compared
against the initial set of matched partitions, and the Hive metastore is
updated to reflect the newly added / removed partitions.
It was necessary to introduce a method for staging files with absolute
output paths to `FileCommitProtocol`. These files are not handled by the Hadoop
output committer but are moved to their final locations when the job commits.
The overwrite behavior of legacy Datasource tables is also changed: no
longer will the entire table be overwritten if a partial partition spec is
present.

[SPARK-13331] AES support for over-the-wire encryption
## What changes were proposed in this pull request?
DIGEST-MD5 mechanism is used for SASL authentication and secure
communication. DIGEST-MD5 mechanism supports 3DES, DES, and RC4 ciphers.
However, 3DES, DES and RC4 are slow relatively.
AES provide better performance and security by design and is a replacement
for 3DES according to NIST. Apache Common Crypto is a cryptographic library
optimized with AES-NI, this patch employ Apache Common Crypto as enc/dec
backend for SASL authentication and secure channel to improve spark RPC.

[SPARK-17982][SQL] SQLBuilder should wrap the generated SQL with
parenthesis for LIMIT
## What changes were proposed in this pull request?
Currently, `SQLBuilder` handles `LIMIT` by always adding `LIMIT` at the end
of the generated subSQL. It makes `RuntimeException`s like the following. This
PR adds a parenthesis always except `SubqueryAlias` is used together with
`LIMIT`.
**Before**
``` scala
scala> sql("CREATE TABLE tbl(id INT)")
scala> sql("CREATE VIEW v1(id2) AS SELECT id FROM tbl LIMIT 2")
java.lang.RuntimeException: Failed to analyze the canonicalized SQL: ...
```
**After**
``` scala
scala> sql("CREATE TABLE tbl(id INT)")
scala> sql("CREATE VIEW v1(id2) AS SELECT id FROM tbl LIMIT 2")
scala> sql("SELECT id2 FROM v1")
res4: org.apache.spark.sql.DataFrame = [id2: int]
```
**Fixed cases in this PR**
The following two cases are the detail query plans having problematic SQL
generations.
1. `SELECT * FROM (SELECT id FROM tbl LIMIT 2)`
Please note that **FROM SELECT** part of the generated SQL in the
below. When we don't use '()' for limit, this fails.
```scala
# Original logical plan:
Project [id#1]
+- GlobalLimit 2
+- LocalLimit 2
+- Project [id#1]
+- MetastoreRelation default, tbl
# Canonicalized logical plan:
Project [gen_attr_0#1 AS id#4]
+- SubqueryAlias tbl
+- Project [gen_attr_0#1]
+- GlobalLimit 2
+- LocalLimit 2
+- Project [gen_attr_0#1]
+- SubqueryAlias gen_subquery_0
+- Project [id#1 AS gen_attr_0#1]
+- SQLTable default, tbl, [id#1]
# Generated SQL:
SELECT `gen_attr_0` AS `id` FROM (SELECT `gen_attr_0` FROM SELECT
`gen_attr_0` FROM (SELECT `id` AS `gen_attr_0` FROM `default`.`tbl`) AS
gen_subquery_0 LIMIT 2) AS tbl
```
2. `SELECT * FROM (SELECT id FROM tbl TABLESAMPLE (2 ROWS))`
Please note that **((~~~) AS gen_subquery_0 LIMIT 2)** in the below.
When we use '()' for limit on `SubqueryAlias`, this fails.
```scala
# Original logical plan:
Project [id#1]
+- Project [id#1]
+- GlobalLimit 2
+- LocalLimit 2
+- MetastoreRelation default, tbl
# Canonicalized logical plan:
Project [gen_attr_0#1 AS id#4]
+- SubqueryAlias tbl
+- Project [gen_attr_0#1]
+- GlobalLimit 2
+- LocalLimit 2
+- SubqueryAlias gen_subquery_0
+- Project [id#1 AS gen_attr_0#1]
+- SQLTable default, tbl, [id#1]
# Generated SQL:
SELECT `gen_attr_0` AS `id` FROM (SELECT `gen_attr_0` FROM ((SELECT `id` AS
`gen_attr_0` FROM `default`.`tbl`) AS gen_subquery_0 LIMIT 2)) AS tbl
```

[SPARK-18060][ML] Avoid unnecessary computation for MLOR
## What changes were proposed in this pull request?
Before this patch, the gradient updates for multinomial logistic regression
were computed by an outer loop over the number of classes and an inner loop
over the number of features. Inside the inner loop, we standardized the feature
value (`value / featuresStd(index)`), which means we performed the computation
`numFeatures * numClasses` times. We only need to perform that computation
`numFeatures` times, however. If we re-order the inner and outer loop, we can
avoid this, but then we lose sequential memory access. In this patch, we
instead lay out the coefficients in column major order while we train, so that
we can avoid the extra computation and retain sequential memory access. We
convert back to row-major order when we create the model.
## How was this patch tested?
This is an implementation detail only, so the original behavior should be
maintained. All tests pass. I ran some performance tests to verify speedups.
The results are below, and show significant speedups.

[SPARK-16759][CORE] Add a configuration property to pass caller contexts of
upstream applications into Spark
## What changes were proposed in this pull request?
Many applications take Spark as a computing engine and run on it. This PR
adds a configuration property `spark.log.callerContext` that can be used by
Spark's upstream applications (e.g. Oozie) to set up their caller contexts into
Spark. In the end, Spark will combine its own caller context with the caller
contexts of its upstream applications, and write them into Yarn RM log and HDFS
audit log.
The audit log has a config to truncate the caller contexts passed in
(default 128). The caller contexts will be sent over rpc, so it should be
concise. The call context written into HDFS log and Yarn log consists of two
parts: the information `A` specified by Spark itself and the value `B` of
`spark.log.callerContext` property. Currently `A` typically takes 64 to 74
characters, so `B` can have up to 50 characters (mentioned in the doc
`running-on-yarn.md`)
## How was this patch tested?
Manual tests. I have run some Spark applications with
`spark.log.callerContext` configuration in Yarn client/cluster mode, and
verified that the caller contexts were written into Yarn RM log and HDFS audit
log correctly.
The ways to configure `spark.log.callerContext` property:
- In spark-defaults.conf:
```
spark.log.callerContext infoSpecifiedByUpstreamApp
```
- In app's source code:
```
val spark = SparkSession
.builder
.appName("SparkKMeans")
.config("spark.log.callerContext", "infoSpecifiedByUpstreamApp")
.getOrCreate()
```
When running on Spark Yarn cluster mode, the driver is unable to pass
'spark.log.callerContext' to Yarn client and AM since Yarn client and AM have
already started before the driver performs `.config("spark.log.callerContext",
"infoSpecifiedByUpstreamApp")`.
The following example shows the command line used to submit a SparkKMeans
application and the corresponding records in Yarn RM log and HDFS audit log.
Command:
```
./bin/spark-submit --verbose --executor-cores 3 --num-executors 1 --master
yarn --deploy-mode client --class org.apache.spark.examples.SparkKMeans

[SPARK-18166][MLLIB] Fix Poisson GLM bug due to wrong requirement of
response values
## What changes were proposed in this pull request?
The current implementation of Poisson GLM seems to allow only positive
values. This is incorrect since the support of Poisson includes the origin. The
bug is easily fixed by changing the test of the Poisson variable from
'require(y **>** 0.0' to 'require(y **>=** 0.0'.

[SPARK-18396][HISTORYSERVER] Duration" column makes search result confused,
maybe we should make it unsearchable
## What changes were proposed in this pull request?
When we search data in History Server, it will check if any columns
contains the search string. Duration is represented as long value in table, so
if we search simple string like "003", "111", the duration containing "003",
â111â will be showed, which make not much sense to users.
We cannot simply transfer the long value to meaning format like "1 h", "3.2
min" because they are also used for sorting. Better way to handle it is ban
"Duration" columns from searching.
## How was this patch tested
manually tests.
Before("local-1478225166651" pass the filter because its duration in long
value, which is "257244245" contains search string "244"):

[SPARK-18416][STRUCTURED STREAMING] Fixed temp file leak in state store
## What changes were proposed in this pull request?
StateStore.get() causes temporary files to be created immediately, even if
the store is not used to make updates for new version. The temp file is not
closed as store.commit() is not called in those cases, thus keeping the output
stream to temp file open forever.
This PR fixes it by opening the temp file only when there are updates being
made.

[SPARK-17348][SQL] Incorrect results from subquery transformation
## What changes were proposed in this pull request?
Return an Analysis exception when there is a correlated non-equality
predicate in a subquery and the correlated column from the outer reference is
not from the immediate parent operator of the subquery. This PR prevents
incorrect results from subquery transformation in such case.
Test cases, both positive and negative tests, are added.
## How was this patch tested?
sql/test, catalyst/test, hive/test, and scenarios that will produce
incorrect results without this PR and product correct results when subquery
transformation does happen.

[SPARK-18124] Observed delay based Event Time Watermarks
This PR adds a new method `withWatermark` to the `Dataset` API, which can
be used specify an _event time watermark_. An event time watermark allows the
streaming engine to reason about the point in time after which we no longer
expect to see late data. This PR also has augmented `StreamExecution` to use
this watermark for several purposes:
- To know when a given time window aggregation is finalized and thus
results can be emitted when using output modes that do not allow updates (e.g.
`Append` mode).
- To minimize the amount of state that we need to keep for on-going
aggregations, by evicting state for groups that are no longer expected to
change. Although, we do still maintain all state if the query requires (i.e.
if the event time is not present in the `groupBy` or when running in `Complete`
mode).
An example that emits windowed counts of records, waiting up to 5 minutes
for late data to arrive.
```scala
df.withWatermark("eventTime", "5 minutes")
.groupBy(window($"eventTime", "1 minute") as 'window)
.count()
.writeStream
.format("console")
.mode("append") // In append mode, we only output finalized aggregations.
.start()
```
### Calculating the watermark.
The current event time is computed by looking at the `MAX(eventTime)` seen
this epoch across all of the partitions in the query minus some user defined
_delayThreshold_. An additional constraint is that the watermark must increase
monotonically.
Note that since we must coordinate this value across partitions
occasionally, the actual watermark used is only guaranteed to be at least
`delay` behind the actual event time. In some cases we may still process
records that arrive more than delay late.
This mechanism was chosen for the initial implementation over processing
time for two reasons:
- it is robust to downtime that could affect processing delay
- it does not require syncing of time or timezones between the producer
and the processing engine.
### Other notable implementation details
- A new trigger metric `eventTimeWatermark` outputs the current value of
the watermark.
- We mark the event time column in the `Attribute` metadata using the key
`spark.watermarkDelay`. This allows downstream operations to know which column
holds the event time. Operations like `window` propagate this metadata.
- `explain()` marks the watermark with a suffix of `-T${delayMs}` to ease
debugging of how this information is propagated.
- Currently, we don't filter out late records, but instead rely on the
state store to avoid emitting records that are both added and filtered in the
same epoch.
### Remaining in this PR
- [ ] The test for recovery is currently failing as we don't record the
watermark used in the offset log. We will need to do so to ensure determinism,
but this is deferred until #15626 is merged.
### Other follow-ups
There are some natural additional features that we should consider for
future work:
- Ability to write records that arrive too late to some external store in
case any out-of-band remediation is required.
- `Update` mode so you can get partial results before a group is evicted.
- Other mechanisms for calculating the watermark. In particular a
watermark based on quantiles would be more robust to outliers.

[SPARK-18430][SQL] Fixed Exception Messages when Hitting an Invocation
Exception of Function Lookup
### What changes were proposed in this pull request?
When the exception is an invocation exception during function lookup, we
return a useless/confusing error message:
For example,
```Scala
df.selectExpr("concat_ws()")
```
Below is the error message we got:
```
null; line 1 pos 0
org.apache.spark.sql.AnalysisException: null; line 1 pos 0
```
To get the meaningful error message, we need to get the cause. The fix is
exactly the same as what we did in https://github.com/apache/spark/pull/12136.
After the fix, the message we got is the exception issued in the constuctor of
function implementation:
```
requirement failed: concat_ws requires at least one argument.; line 1 pos 0
org.apache.spark.sql.AnalysisException: requirement failed: concat_ws
requires at least one argument.; line 1 pos 0
```
### How was this patch tested?
