[jira] [Created] (HBASE-25829) SPLIT state detritus
Andrew Kyle Purtell created HBASE-25829:
-------------------------------------------
Summary: SPLIT state detritus
Key: HBASE-25829
URL: https://issues.apache.org/jira/browse/HBASE-25829
Project: HBase
Issue Type: Bug
Affects Versions: 2.4.3
Reporter: Andrew Kyle Purtell
Fix For: 3.0.0-alpha-1, 2.5.0, 2.4.3
Seen after an integration test load with 'calm' monkey, so this happened in the happy path.
There were no errors accessing all loaded table data, however whenever the balancer runs there are a number of concerning INFO level log messages printed of the form _assignment.RegionStates: Skipping, no server for state=SPLIT, location=null, table=TABLENAME_
For example:

The HBCK chore notices them but does nothing:
"Loaded *80 regions *from in-memory state of AssignmentManager"
"Loaded *73 regions from 5 regionservers' reports* and found 0 orphan regions"
"Loaded 3 tables 80 regions from filesystem and found 0 orphan regions"
{noformat}
