metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java (line 3267)


Instead of making this check, we should just try to persist the row in 
constraint table, it will fail in case there is a duplicate name, since its a 
part of primary key, in which case we pick another name.



metastore/src/model/org/apache/hadoop/hive/metastore/model/MConstraintPK.java 
(line 7)


I don't see this class getting used anywhere. In jdo mapping its seems you 
are using inner class PK which is defined in MConstraint. Do we need both?

[jira] [Created] (HIVE-13523) Fix connection leak in ORC RecordReader and refactor for unit testing

2016-04-14 Thread Thomas Poepping (JIRA)

 Summary: Fix connection leak in ORC RecordReader and refactor for 
unit testing
 Key: HIVE-13523
 URL: https://issues.apache.org/jira/browse/HIVE-13523
 Project: Hive
  Issue Type: Bug
  Components: ORC
Affects Versions: 2.0.0
Reporter: Thomas Poepping


In RecordReaderImpl, a MetadataReaderImpl object was being created (opening a 
file), but never closed, causing a leak. This change closes the Metadata object 
in RecordReaderImpl, and does substantial refactoring to make RecordReaderImpl 
testable:
 * Created DataReaderFactory and MetadataReaderFactory (plus default 
implementations) so that the create() methods can be mocked to verify that the 
objects are actually closed in RecordReaderImpl.close()
 * Created MetadataReaderProperties and DataReaderProperties to clean up 
argument lists, making code more readable
 * Created a builder() for RecordReaderImpl to make the code more readable
 * DataReader and MetadataReader now extend closeable (there was no reason for 
them not to in the first place) so I can use the guava Closer interface: 
http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/io/Closer.html
 * Use the Closer interface to guarantee that regardless of if either close() 
call fails, both will be attempted (preventing further potential leaks)
 * Create builders for MetadataReaderProperties, DataReaderProperties, and 
RecordReaderImpl to help with code readability

Current timeout for batches is 2hours. This needs to be lowered. 1hour may be 
too much as well. We can start with this, and reduce timeouts further.

Add a row interface for the LlapRecordReader, so the client doesn't have to

Also move away from using metastore Schema class, to avoid dependency on 
metastore.

Currently the big table is always assumed to be at position 0 but this isn't 
efficient for some queries as the big table at position 1 could have a lot more 
keys/skew. We already have a mechanism of choosing the big table that can be 
leveraged to make the right choice.

In Spark, there might be more than one task running in one executor. Similarly, 
there may be more than one thread running in Driver.

This makes debugging through the logs a nightmare. It would be great if there 
could be thread-ids in the logs.

 Summary: Semantics of TypeInfoUtils.areColTypesCompatible changed 
which also changed the semantics of 
hive.metastore.disallow.incompatible.col.type.changes of 
 Key: HIVE-13515
 URL: https://issues.apache.org/jira/browse/HIVE-13515
 Project: Hive
  Issue Type: Bug
  Components: Hive
Affects Versions: 2.1.0
Reporter: Matt McCline
Assignee: Ashutosh Chauhan
Priority: Critical



I had this test case in my new Schema Evolution patch (not checked in yet) that 
verifies STRING_GROUP to DECIMAL conversion:

{code}
-- SUBSECTION: ALTER TABLE CHANGE COLUMNS for STRING_GROUP -> DECIMAL: (STRING, 
CHAR, VARCHAR)
--
CREATE TABLE table_change_string_group_decimal(insert_num int, c1 STRING, c2 
CHAR(50), c3 VARCHAR(50), b STRING);

insert into table table_change_string_group_decimal
values (1, '753.7028', '753.7028', '753.7028', 'original'),
   (2, '-3651.672121', '-3651.672121', '-3651.672121', 'original'),
   (3, '-29.0764', '-29.0764', '-29.0764', 'original'),
   (4, '-10.3', '-10.3', '-10.3', 'original');

-- Table-Non-Cascade CHANGE COLUMNS ...
alter table table_change_string_group_decimal replace columns (insert_num int, 
c1 decimal(38,18), c2 decimal(38,18), c3 decimal(38,18), b STRING);

insert into table table_change_string_group_decimal
 values (5, 30.774, 30.774, 30.774, 'new'),
(6, 20.31, 20.31, 20.31, 'new'),
(7, 46114.284799488, 46114.284799488, 46114.284799488, 'new'),
(8, -66475.561431, -66475.561431, -66475.561431, 'new');

insert into table table_change_string_group_decimal
 values (9, 17808.963785, 17808.963785, 17808.963785, 'new'),
(10, 9250340.75 , 9250340.75 , 9250340.75 , 'new');

explain
select insert_num,c1,c2,c3,b from table_change_string_group_decimal order by 
insert_num;

select insert_num,c1,c2,c3,b from table_change_string_group_decimal order by 
insert_num;

drop table table_change_string_group_decimal;
{code}

that now fails on master (I suspect because of HIVE-13380 Decimal should have 
lower precedence than double in type hierachy) when:

{code}
set hive.metastore.disallow.incompatible.col.type.changes=true;
{code}

with this call stack:
{code}
Caused by: InvalidOperationException(message:The following columns have types 
incompatible with the existing columns in their respective positions :
c1,c2,c3)
at 
org.apache.hadoop.hive.metastore.MetaStoreUtils.throwExceptionIfIncompatibleColTypeChange(MetaStoreUtils.java:599)
at 
org.apache.hadoop.hive.metastore.HiveAlterHandler.alterTable(HiveAlterHandler.java:132)
at 
org.apache.hadoop.hive.metastore.HiveMetaStore$HMSHandler.alter_table_core(HiveMetaStore.java:3502)
at 
org.apache.hadoop.hive.metastore.HiveMetaStore$HMSHandler.alter_table_with_environment_context(HiveMetaStore.java:3473)
{code}

Key point is MetaStoreUtils.throwExceptionIfIncompatibleColTypeChange is 
calling TypeInfoUtils.areColTypesCompatible which changed

-// Allow implicit String to Decimal conversion
-if (fromPg == PrimitiveGrouping.STRING_GROUP && to == 
PrimitiveCategory.DECIMAL) {
-  return true;
-}

Will not current customers that have scripts with 
hive.metastore.disallow.incompatible.col.type.changes=true that do Schema 
Evolution get bitten?

TestClearDanglingScratchDir fail on branch-1 due to branch-1 is using log4j. 
Attach a patch to let test pass on both master and branch-1.
