[jira] [Created] (PHOENIX-3576) ParallelWriterIndexCommitter should fail fast when writing the local index to the closing table

ChiaPing Tsai created PHOENIX-3576:
--------------------------------------

             Summary: ParallelWriterIndexCommitter should fail fast when writing the local index to the closing table
                 Key: PHOENIX-3576
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3576
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.9.0
            Reporter: ChiaPing Tsai


ParallelWriterIndexCommitter uses the AP to update the local index after the region#batchMutate fails. If the region is splitting, all later updates will fail (RegionTooBusyException) due to the write lock. The AP will retry the failed updates until it reaches the retry threshold, so the read lock of region is released after a long time. The read lock blocks the HRegion#close, so the region splitting is also blocked.
