OPTS arguments are duplicated
-----------------------------
Key: HBASE-3561
URL: https://issues.apache.org/jira/browse/HBASE-3561
Project: HBase
Issue Type: Bug
Components: scripts
Reporter: Tim Sell
Priority: Trivial
Some of the command line arguments constructed in the bash scripts are getting
duplicated
Here is what my HMaster process looks like with a ps aux | grep java.

{code}
This wouldn't really be a problem except if you try to add a java agent in the
hbase-env.sh like so:
{code}
export HBASE_MASTER_OPTS="$HBASE_MASTER_OPTS $HBASE_JMX_BASE
-Dcom.sun.management.jmxremote.port=10101 -javaagent:HelloWorldAgent.jar"
{code}
It adds the option 3 times and it starts three java agents. My example agent
print hello world once per second, but I end up with three hello world lines
per second.
I attached my HelloWorldAgent.jar to demonstrate.
