Subject [jira] [Commented] (HBASE-19744) Fix flakey TestZKLeaderManager

Duo Zhang commented on HBASE-19744:
-----------------------------------

We still use it in AuthenticationTokenSecretManager. Do not know why it is marked as deprecated
since there is no alternate.

> On my little cluster, zk runs slow for whatever reason (TBD). This test always fails
on me. Looking at it, there is at least a race given we stop mock masters and then put them
on line again immediately... Testing if a thread Master is not going to give right answer
always. Also, given zk runs slow on this host, just up the timeouts and number of Masters
available. Sloppy but more likely to succeed (This test is for a deprecated class...)
