Description

As a stopgap before PHOENIX-3520, we can create an HBase WALEntryFilter to filter out non-tenant rows of SYSTEM.CATALOG from replication while allowing tenant-owned rows such as tenant views to proceed with replication.

This would have to be incorporated into a ReplicationEndpoint subclass to be useful, though HBASE-17543 would make that much simpler by doing it via configuration rather than code (and avoiding the need for a new peer to be created).

If PHOENIX-3520 is on the near-future roadmap, however, that would be the better solution to the "replication corrupts SYSTEM.CATALOG" problem.
