Ted Yu commented on HBASE-14623:
--------------------------------
I can think of 3 strategies for implementing system WAL:
1. one WAL for all non-meta system tables
2. one WAL for each non-meta system table
3. one WAL for each region of non-meta system table
To enable 2 and 3, we need to pass more information to WALProvider#getWAL().
{code}
WAL getWAL(final byte[] identifier, byte[] namespace) throws IOException;
{code}
For #2, table name should be passed.
For #3, HRegionInfo should be passed.

> As Stephen suggested in parent JIRA, dedicating separate WAL for system
> tables (other than hbase:meta) should be done in new JIRA.
> This task is to fulfill the system WAL separation.
