Hi esteban, I don't have access to HBase master logs but I'll try to get it if I can. When the failover occurs only the hbase service goes down. We see the standby Master being active.
The clients run on different nodes and have the zookeeper configured correctly. Here is the post I have on stackoverflow to give more information about the error and the hbase-site.xml configuration. http://stackoverflow.com/questions/24726994/hbase-failover-situation cheers, Jinal On Mon, Jul 14, 2014 at 12:10 AM, Esteban Gutierrez <este...@cloudera.com> wrote: > -dev (bcc) +user > > Hello Jinal, > > Can you pastebin the logs from both HBase masters?
