Peter Somogyi updated HBASE-24206:
----------------------------------
Status: Patch Available (was: Open)
> Unsupported rollback should not be logged as CODE-BUG
> ------------------------------------------------------
>
> Key: HBASE-24206
> URL: https://issues.apache.org/jira/browse/HBASE-24206
> Project: HBase
> Issue Type: Improvement
> Components: logging, proc-v2
> Reporter: Peter Somogyi
> Assignee: Peter Somogyi
> Priority: Minor
>
> When executing rollback from a state that does not support rollback
> functionality UnsupportedOperationException is thrown. The Procedure
> framework does not handle this case specially and logs an ERROR message
> because it is caught as a Throwable.
> This scenario should have a cleaner log message.
