Nick Dimiduk updated HBASE-27762:
---------------------------------
Release Note:
<!-- markdown -->
Log the `o.a.h.hbase.executor.EventType` and ProcedureV2 pid in log messages
via MDC. PatternLayouts on master and branch-2 have been updated to make use of
the MDC variables. Note that due to LOG4J2-3660, log lines for which the MDC is
empty will have extraneous characters. To opt-in on branch-2.5 or branch-2.4,
make an appropriate change to `conf/log4j2.properties`.

> Tracing the distributed actions of ProcedureV2 {{RemoteProcedure}} execution
> is painful. We are pretty good about logging the {{proc_id}} most of the
> time, but we don't catch them all. Now that we're up on log4j2, let's use the
> MDC feature to include some basic information universally.
