Peter Somogyi updated HBASE-18108:
----------------------------------
Release Note:
The archived Procedure WALs are moved to
<hbase_root>/oldWALs/masterProcedureWALs
directory. TimeToLiveProcedureWALCleaner class was added which regularly cleans
the Procedure WAL files from there.
The TimeToLiveProcedureWALCleaner is added to hbase.master.logcleaner.plugins
configuration value.
A new config parameter is added: hbase.master.procedurewalcleaner.ttl, which
specifies how long a Procedure WAL should stay in the archive directory.

> The Procedure WAL files used to be deleted when done. HBASE-14614 keeps them
> around in case issue but what is missing is a GC for no-longer-needed WAL
