-------------------------------------------
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.
