Ashish Singhi updated HBASE-9964:
---------------------------------
Attachment: HBASE-9964.patch
I faced the same issue when I configured non advisable value *0.9* to
*hbase.regionserver.global.memstore.size* and then executed hbase-daemon.sh
start master.
Master process startup failed with a RuntimeException logged in the log file
but the script exit code was zero, which I felt is not correct.
Attaching a simple patch for this issue. The fix I have done is after start
command is sent to the main class we will sleep for 3 seconds and check whether
the background process is still running if it is not running then exit the
script with non zero exit code.
Generally if any configuration is miss configured then java process may
terminate with in 3 seconds.
> start-hbase.sh returns success exit status and emits "starting master"
> message when master failed to start

> The bin/start-hbase.sh script returns an exit status indicating success, and
> emits the message : 'starting master, logging to ...' , even though the
> master failed to start:
> $ ./bin/start-hbase.sh
> starting master, logging to
> /home/jason/3P/hbase-0.94.13/logs/hbase-jason-master-jvds.out
> $ echo $?
> 0
> # ^- this indicates successful exit status on Linux / UNIX-like systems

> java.lang.RuntimeException: Failed suppression of fs shutdown hook:
> Thread[Thread-27,5,main]
> The start-base.sh script should IMHO in the above scenario emit a message
> like
> 'Failed to start the hbase master: java.lang.RuntimeException: Failed
> suppression of fs shutdown hook'
> and return a non-zero exit status.
