HBase masters file

["Sudarshan Kadambi (BLOOMBERG/ 731 LEXIN)" <sk...@bloomberg.net>]

HBase 0.92 used to have a /etc/hbase/conf/masters file, which contained the location of the HBase master. Has this file been removed in HBase 0.94.6? I see the regionservers file, but not the masters file in our deployment.

I also used the zoookeeper-client to browse the /hbase subtree. The /hbase/master znode is missing as well.

Is something mis-configured in our cluster? HBase looks to be functional - and I'm wondering how that is if I can't find any reference to the master node hostname in the configs.

Hi Sudarshan,

Are you using 0.94.6? Or 0.94.6.1? The former is not recommend.

regarding the master file, no, it's not required anymore, so you can
stop looking for it ;)

Regarding the ZK nodes, sorry, I don't know how it was in 0.92 so I
can't compare.
