confused behavior about pyspark.sql, Row, schema, and createDataFrame
python version: 2.7.9
os: ubuntu 14.04
spark: 1.5.2
```
import pyspark
from pyspark.sql import Row
from pyspark.sql.types import StructType, IntegerType
sc = pyspark.SparkContext()
sqlc = pyspark.SQLContext(sc)
schema1 = StructType() \
.add('a', IntegerType()) \
.add('b', IntegerType())
schema2 = StructType() \
.add('b', IntegerType()) \
.add('a', IntegerType())
print(schema1 == schema2)
r1 = Row(a=1, b=2)
r2 = Row(b=2, a=1)
print(r1 == r2)
data = [r1, r2]
df1 = sqlc.createDataFrame(data, schema1)
df1.show()
df2 = sqlc.createDataFrame(data, schema2)
df2.show()
```
intuitively, I thought df1 and df2 should contain the same data, however,
the output is
```
False
True
+---+---+
| a| b|
+---+---+
| 1| 2|
| 1| 2|
+---+---+
+---+---+
| b| a|
+---+---+
| 1| 2|
| 1| 2|
+---+---+
```
after trace the source code, I found
1. schema (StructType) use list store fields, so it is order-sensitive
https://github.com/apache/spark/blob/master/python/pyspark/sql/types.py#L459
2. Row will sort according to field name when new
https://github.com/apache/spark/blob/master/python/pyspark/sql/types.py#L1204
3. It seems (not 100% sure) that when createDataFrame, it access the filed
of Row by order not by filed name
https://github.com/apache/spark/blob/master/python/pyspark/sql/context.py#L422
This behavior is a little bit tricky. Maybe this behavior could be mention
at document?
Thanks.

value of sc.defaultParallelism
python version: 2.7.9 os: ubuntu 14.04 spark: 1.5.2 I run a standalone spark on localhost, and use the following code to access sc.defaultParallism # a.py import pyspark sc = pyspark.SparkContext() print(sc.defaultParallelism) and use the following command to submit $ spark-submit --master spark://yahsuan-vm:7077 a.py it prints 2, however, my spark web page shows I got 4 cores according to http://spark.apache.org/docs/latest/configuration.html spark.default.parallelismFor distributed shuffle operations likereduceByKey and join, the largest number of partitions in a parent RDD. For operations likeparallelize with no parent RDDs, it depends on the cluster manager: - Local mode: number of cores on the local machine - Mesos fine grained mode: 8 - Others: total number of cores on all executor nodes or 2, whichever is larger Default number of partitions in RDDs returned by transformations like join, reduceByKey, andparallelize when not set by user. It seems I should get 4 rather than 2. Am I misunderstood the document? -- -- 張雅軒
Re: does spark really support label expr like && or || ?
are you trying to do dataframe boolean expression? please use '&' for 'and', '|' for 'or', '~' for 'not' when building DataFrame boolean expressions. example: >>> df = sqlContext.range(10) >>> df.where( (df.id==1) | ~(df.id==1)) DataFrame[id: bigint] On Wed, Dec 16, 2015 at 4:32 PM, Allen Zhang wrote: > Hi All, > > does spark label expression really support "&&" or "||" or even "!" for > label based schedulering? > I tried that but it does NOT work. > > Best Regards, > Allen > > -- -- 張雅軒
