Subject [jira] [Commented] (PIG-5283) Configuration is not passed to SparkPigSplits on the backend
Date Thu, 03 Aug 2017 09:00:09 GMT

    [ https://issues.apache.org/jira/browse/PIG-5283?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16112449#comment-16112449

liyunzhang_intel commented on PIG-5283:

[~szita]: In  [PigInputFormatSpark#createRecordReader|https://github.com/apache/pig/blob/trunk/src/org/apache/pig/backend/hadoop/executionengine/spark/running/PigInputFormatSpark.java#L59],
 it  initialize pigSplit configuration.  In my understanding,the configuration of pigSplit
is initialized correctly, so currently you met a problem of invalid initialization of pigSplit's
configuration?  If yes, can you provide simple script to show your problem.

> When a Hadoop ObjectWritable is created during a Spark job, the instantiated PigSplit
(wrapped into a SparkPigSplit) is given an empty Configuration instance.
