-------------------------------------
Summary: Improved logging when interrupting active RPC handlers
holding the region close lock (HBASE-25212 hbase.regionserver.close.wait.abort)
Key: HBASE-25749
URL: https://issues.apache.org/jira/browse/HBASE-25749
Project: HBase
Issue Type: Bug
Components: regionserver, rpc
Affects Versions: 2.4.0, 3.0.0-alpha-1, 1.7.0
Reporter: David Manning
HBASE-25212 adds an optional improvement to Close Region, for interrupting
active RPC handlers holding the region close lock. If, after the timeout is
reached, the close lock can still not be acquired, the regionserver may abort.
It would be helpful to add logging for which threads or components are holding
the region close lock at this time.
Depending on the size of regionLockHolders, or use of any stack traces, log
output may need to be truncated. The interrupt code is in
HRegion#interruptRegionOperations.
