--------------------------------------
Summary: Storage class aware block placement for procedure v2 WALs
Key: HBASE-18015
URL: https://issues.apache.org/jira/browse/HBASE-18015
Project: HBase
Issue Type: Improvement
Affects Versions: 2.0.0
Reporter: Andrew Purtell
Assignee: Andrew Purtell
Priority: Minor
After HBASE-14061, HBASE-15172, and HBASE-17538, we can specify storage class
placement policies for store files and WAL files. However, we missed procedure
v2 WALs aka "MasterProcWAL", opened and updated by the master. We should apply
the same storage policy for procv2 WALs as we do for regionserver WALs,
specified by the HConstants.WAL_STORAGE_POLICY configuration key, using
HConstants.DEFAULT_WAL_STORAGE_POLICY as default.
