-------------------------------------------
Summary: Log stuck/long-running procedures for visibility
Key: HBASE-29581
URL: https://issues.apache.org/jira/browse/HBASE-29581
Project: HBase
Issue Type: Improvement
Components: master, proc-v2
Affects Versions: 2.6.3, 3.0.0
Reporter: Umesh Kumar Kumawat
Assignee: Umesh Kumar Kumawat
There are many cases when some procedures get stuck or running for a long time,
but there are no warning logs for these. Without these logs it is difficult to
find the right way to remediate. For now we can go and check on HMaster UI but
there also one need to pay attention to all the procedures that are running and
find out ones that have issue.
In our case 2 SplitWalProcedure got stuck somehow. After these procedures got
created I don't see any logs for these, no worker pikced these procedures.
Procedure stayed stuck until we did the HMaser failover.
It would be good if we have warning logs for such procedures. That we can
recover from the issue quickly
