Subject [jira] [Updated] (HIVE-7776) enable sample10.q.[Spark Branch]
Date Wed, 10 Sep 2014 08:45:29 GMT


Chengxiang Li updated HIVE-7776:
    Attachment: HIVE-7776.1-spark.patch

Hive get task Id through 2 ways in Utilities::getTaskId:
# get parameter value of from configuration.
# generate random value while #1 return null.
Currently, Hive on Spark can't get parameter value of from configuration.

FileSinkOperator use taskid to distinct different bucket file name, FileSinkOperator should
take taskid as field variable and initiate it only once since one FileSinkOperator instance
only refered in one task. but FileSinkOperator call Utilities::getTaskId to get new taskId
each time, for this issue, it would cause more bucket files than bucket number, which lead
to unexpected result of tablesample queries.
