Jonathan Gray commented on HBASE-1614:
--------------------------------------
I vote that we close this issue as fixed or invalid. It was fixed from other
ZK fixes, namely not asking for ROOT location every time.
0.21 usage of ZK will expand greatly and if this happens again it should be
dealt with in another jira.
> single zk node buckling under small node? connections never timing out?

> Project: Hadoop HBase
> Issue Type: Bug
> Reporter: stack
> Fix For: 0.21.0
>
>
> A few (Irfan on the list and jgray) report that a single node zk seems
> insufficient supporting small cluster < 20 nodes. This seems odd (though,
> yeah, we're recommending serious deploys must have a quorum of >= 3 zk
> nodes). Also, reports that all connections fill up and don't time out though
> job is done (on IRC). Take a look.
> (Check zk stat to see if it'll dump connections)
