[jira] [Created] (HBASE-20568) Concurrency issue for CombinedAsyncWriter

Duo Zhang created HBASE-20568:
---------------------------------

             Summary: Concurrency issue for CombinedAsyncWriter
                 Key: HBASE-20568
                 URL: https://issues.apache.org/jira/browse/HBASE-20568
             Project: HBase
          Issue Type: Sub-task
            Reporter: Duo Zhang


In sequential mode, we need to wait for the previous writer's sync completes before issue the sync for the next writer. But the sync request is asynchronous, so we will return immediately and then we can call append, so it is possible that we call append and sync at the same time and cause concurrency issues.
