> 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.
