Subject Too many znodes and the zk_avg_latency is large
Date Wed, 17 Sep 2014 12:07:47 GMT
We use ZooKeeper for HBase and HBase replication has leaved too many HLogs
which are recorded in ZooKeeper. Now we have more than 1M watches and the
the average latency from `mntr` is almost 3000. The ZooKeeper cluster seems
to be unstable and the client occasionally fail to set data on znodes.

How can I reduce the latency from ZooKeeper? Is it mainly related to the
number of znodes?
