Tim Sell commented on HBASE-3561:
---------------------------------
hmm, unless I missed something, this doesn't work with the start-hbase.sh
script it doesn't seem to load hbase-env.sh at all. Not in standalone mode
anyway.
> OPTS arguments are duplicated

> 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:lib/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.
