[jira] [Created] (HBASE-25835) Ignore duplicate split requests from regionserver reports

Andrew Kyle Purtell created HBASE-25835:
-------------------------------------------

             Summary: Ignore duplicate split requests from regionserver reports
                 Key: HBASE-25835
                 URL: https://issues.apache.org/jira/browse/HBASE-25835
             Project: HBase
          Issue Type: Sub-task
    Affects Versions: 2.4.3
            Reporter: Andrew Kyle Purtell
            Assignee: Andrew Kyle Purtell
             Fix For: 3.0.0-alpha-1, 2.5.0, 2.4.3


A SplitTableRegionProcedure may already be running when a regionserver report is received that includes a split request. The outcome is multiple SplitTableRegionProcedure procedures scheduled for the split request, only one of which can succeed. The others error out. Perhaps it is only WARN level noise in the logs that will cause operator concern, but is clearly not correct. 

Do not create a split procedure in response to a region state change report if the region is not open or already splitting.
