duplicate HBASE_OPTS
Hi,
I'm using trunk
I've been trying to pass a javaagent in by configuring it in hbase-env.sh
I've noticed some weird behaviour. It seems to start three agents,
which with the agent I really want to use seems to be breaking it, it
never quite starts.
I created a hello world agent and I noticed that all the options seem
to be set three times.
The only thing I changed was adding the -javaagent to HBASE_MASTER_OPTS like so:
export HBASE_MASTER_OPTS="$HBASE_MASTER_OPTS $HBASE_JMX_BASE
-Dcom.sun.management.jmxremote.port=10101
-javaagent:/Users/tims/workspace/HelloWorldAgent/target/HelloWorldAgent-0.0.1-SNAPSHOT.jar"
I ran ps aux | grep java, here's what the master looks like.
/Library/Java/Home/bin/java

-XX:+CMSIncrementalMode

etc
etc
org.apache.hadoop.hbase.master.HMaster start
I started the master without the java agent and yes indeed a bunch of
options are replicated three times.
I couldn't figure out the place where this is happening. Any ideas?

To clarify,
Having the options duplicated wouldn't really be a problem, except
when javaagent is duped I get three agents started.
To demonstrate I made this:
https://github.com/tims/HelloWorldAgent
It prints hello world once per second, but I'm getting 3 lines printed
every second.
I have made a jira for this here:
https://issues.apache.org/jira/browse/HBASE-3561
