Re: HMASTER Service not running

The one that is for the process which died (hbase-master).

Re: HMASTER Service not running

if the log files are indexed, as log1 log2 and log. Select the file which doesn't have any index that is /hbase/logs/...master.log

In this file, you may check if the server connection is set properly or not with respect to zookeeper, It may throw you an error at server connection refused, you may find some solution here, http://wiki.apache.org/hadoop/ConnectionRefused,
