Karthick Sankarachary commented on HBASE-3773:
----------------------------------------------
Just FYI, HBASE-3777 attempts to address the underlying ZK connection overload
issue, and one of the things that it does is set the max connections per IP
(viz., HConnectionManager#MAX_CACHED_HBASE_INSTANCES) to the value specified in
""hbase.zookeeper.property.maxClientCnxns". Please let me know if that's the
way to go.
> Set ZK max connections much higher in 0.90

> Key: HBASE-3773
> URL: https://issues.apache.org/jira/browse/HBASE-3773
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.90.2
> Reporter: Jean-Daniel Cryans
> Assignee: Jean-Daniel Cryans
> Priority: Blocker
> Fix For: 0.90.3

> I think by now we can all acknowledge that 0.90 has an issue with ZK
> connections, in that we create too many of them and it's also too easy for
> our users to shoot themselves in the foot.
> For 0.90.3, I think we should change the default configuration of 30 that we
> ship with and set it much much higher, I'm thinking of 32k.
