Aniket Kulkarni created SPARK-17550:
---------------------------------------
Summary: DataFrameWriter.partitionBy() should throw exception if
column is not present in Dataframe
Key: SPARK-17550
URL: https://issues.apache.org/jira/browse/SPARK-17550
Project: Spark
Issue Type: Bug
Components: Spark Core
Reporter: Aniket Kulkarni
Priority: Minor
I have a spark job which performs certain computations on event data and
eventually persists it to hive.
I was trying to write to hive using the code snippet shown below :
dataframe.write.format("orc").partitionBy(col1,col2).options(options).mode(SaveMode.Append).saveAsTable(hiveTable)
The write to hive was not working as col2 in the above example was not present
in the dataframe. It was a little tedious to debug this as no exception or
message showed up in the logs. I was constantly seeing executor lost failures
in the logs and nothing more.
I think there should be an exception thrown when one tries to write to hive on
a partitioning column that does not exist.
If this is indeed something that needs to be fixed, I would like to volunteer
to fix this in the spark-core code base.
