Subject [jira] [Commented] (HBASE-9468) Previous active master can still serves RPC request when it is trying recovering expired zk session
Date Tue, 10 Sep 2013 03:24:52 GMT

-------------------------------------

[~enis] I agree with you :-). not sure if there is further concern of the recovering logic
for expired master.

> When the active master's zk session expires, it'll try to recover zk session, but without
turn off its RpcServer. What if a previous backup master has already become the now active
master, and some client tries to send request to this expired master by using the cached master
info? Any problem here?
