Subject [jira] [Updated] (HIVE-14042) Potential improvements to abort task handling - tez/llap
Date Fri, 17 Jun 2016 01:51:05 GMT

     [ https://issues.apache.org/jira/browse/HIVE-14042?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Siddharth Seth updated HIVE-14042:
----------------------------------
    Description: 
Follow up from HIVE-14003.

- TezProcessor.run() - in case of an abort, throw an interrupt exception instead of falling
off. (Falling off cleanly indicates success)
- Potential cleanup when initialize exits early
- MapRecordProcessor: MultiMRInput - waitForAllInputsReady can block if interrupts are swallowed
elsewhere. Use changes from TEZ-3302.
- MapRecordProcessor: mergeMapOp handling - this will never be informed about an abort request
- MapRecordProcessor: Likewise, handling of dummyOp
- MapRecordProcessor: Abort handling in MergeFileRecordProcessor
- ReduceRecordProcessor: waitForAllInputsReady. Loop and timed wait after TEZ-3302
- ReduceRecordProcessor: dummyOp handling

  was:
Follow up from HIVE-14003.
