> URL: https://issues.apache.org/jira/browse/HIVE-8704
> Project: Hive
> Issue Type: Bug
> Components: StorageHandler
> Affects Versions: 0.14.0
> Reporter: Sushanth Sowmyan
> Assignee: Sushanth Sowmyan
> Attachments: HIVE-8704.patch
>
>
> HivePassThroughOutputFormat is a wrapper HiveOutputFormat used by hive to
> allow access to StorageHandlers that use mapred OutputFormats as their
> primary implementation point, and do not implement HiveOutputFormat.
> However, HivePassThroughOutputFormat(henceforth called PTOF) has one major
> bug - it tracks the underlying outputformat that it is proxying by means of a
> static string in HiveFileFormatUtils. There are a few problems with this.
> a) For starters, it means that a given process can only process one
> PTOF-based output format. So, in the case of a HS2 instance, where one thread
> is attempting to start a job based on HBase and another on Accumulo will
> cause a problem, and will overwrite each others' "real" output format. This
> leads to bugs where a person trying to use a hbase table gets stack traces
> from Accumulo like the following:
> {noformat}
> ERROR exec.Task: Job Submission failed with exception
> 'java.lang.NullPointerException(Expected Accumulo table name to be provided
> in job configuration)'

> b) There is a bug in HiveFileFormatUtils.getOutputFormatSubstitute, which,
> after it determines that PTOF should act as a substitute for a process, winds
> up registering PTOF in the substitute map. This seems innocuous, but in
> result, because it winds up registering it as a substitute, winds up
> short-circuiting and avoiding the path where it sets the real OF the next
> time. This is a problem, because if the same job were to prepare writing to a
> HBase table, then followed by preparing to write to an Accumulo table,
> followed by preparing to write to a HBase table, then the second time HBase
> comes along, the underlying "real" OF is set to accumulo, and the HBase map
> look up short circuits and avoids the path that would reset the real OF back
> to HBase.
