Nicolas Liochon resolved HBASE-6058.
------------------------------------
Resolution: Won't Fix
> Use ZK 3.4 API 'multi' in bulk assignment
> -----------------------------------------
>
> Key: HBASE-6058
> URL: https://issues.apache.org/jira/browse/HBASE-6058
> Project: HBase
> Issue Type: Improvement
> Components: master, Zookeeper
> Affects Versions: 0.95.2
> Reporter: Nicolas Liochon
> Assignee: Nicolas Liochon
> Priority: Minor
>
> We use async API today. This is already much much faster than the sync API. Still, it makes sense to use the 'multi' function: this will decrease the network & zookeeper load at startup/rolling restart.
> On a 500 nodes cluster, we see 3 that 3 seconds are spent on updating ZK per bulk assignment. This should cut it in half (+ the benefits on the network/zk load).
