Subject Zookeeper Implementation
Date Mon, 15 Jul 2013 18:04:09 GMT
Hello,

I'm running a small cluster of 10 tablet servers and 5 zookeeper nodes (CDH 4.3, Zookeeper
3.4.5, Accumulo 1.5.0).

I have noticed that when a zookeeper node dies, the connected tablet server clients also die
instead of failing-over to another zookeeper. If the clients on the failed zookeeper are only
tablet servers, Accumulo reassigns the tablets. If the Accumulo Master is one of the clients
on the failed node, then the master goes down and the cluster with it.

Anyone else have this problem or know of a workaround/solution to keep the cluster up when
zookeeper changes state?

Thanks,
Drew
