stack commented on HBASE-7723:
------------------------------
I was thinking of those places out in scripts and tools where we want to get to
hdfs where the config may have the single nn format but we're running the ha nn
-- or vice versa. Should just work rather than complain. I suppose lets just
cross that bridge when we come to it.
> Remove NN URI from ZK splitlogs.

> When moving to HDFS HA or removing HA we end up changing the NN namespace.
> This can cause the HMaster not to start up fully due to trying to split
> phantom HLogs pointing to the wrong FS - java.lang.IllegalArgumentException:
> Wrong FS: error messages. The HLogs in question might not even be on HDFS
> anymore. You have to go in a manually clear out the ZK splitlogs directory
> to get HBase to properly boot up.
