Duo Zhang commented on HBASE-19925:
-----------------------------------
And mind adding a test for this? Now we only test the scenario where we even do
not have the correct zk so it will be stuck in the first loop for creating
ReplicationEndpoint.
Oh, the first loop have the same problem... It will just exit the loop if
source is inactive... Maybe we should also change it to a 'for(;;)' loop, and
if we find that the source is inactive, we just return, instead of break.
Thanks.
