> We are on Phoenix 4.14-cdh5.11.  We are experiencing an issue where local index data
is not being replicated through HBase replication.  As suggested in a previous email thread
(https://lists.apache.org/thread.html/984fba3c8abd944846deefb3ea285195e0436b9181b9779feac39b59@%3Cuser.phoenix.apache.org%3E),
we have enabled replication for the local indexes (the "L#0" column family on the same table).
 We wrote an integration test to demonstrate this issue on top of 4.14-cdh5.11 branch (https://github.com/hnguyen08/phoenix/commit/3589cb45d941c6909fb3deb5f5abb0f8dfa78dd7).
> After some investigation and debugging, we discovered the following:
> 1. Commit a2f4d7eebec621b58204a9eb78d552f18dcbcf24 (PHOENIX-3827) fixed the issue, but
only in Phoenix for HBase1.3+.  It uses the miniBatchOp.addOperationsFromCP() API introduced
in HBase1.3.  Unfortunately, for the time being, we are stuck on cdh5.11 (based on HBase1.2).
> 2. IndexUtil.writeLocalUpdates() is called in both implementations of IndexCommitter,
both taking skipWAL=true.  It seems like we'd actually want to not skip WAL to ensure that
local-index updates are replicated correctly (since, as mentioned in the above email thread,
"HBase-level replication of the data table will not trigger index updates").  After changing
the skipWAL flag to false, the above integration test passes.
