Yeah, I wanted to make this point too. ACCUMULO_OTHER_OPTS is only 
relevant if you're using the `accumulo` command to run your code. I 
don't think I would call it "common" for client applications to be 
runnable by the `accumulo` script -- most times your code is completely 
disjoint from the servers.

If you're launching it yourself, you would need to set the proper JVM 
heap/GC properties on your own: e.g. increase -Xmx, turn on 
-XX:+UseConcMarkSweepGC. These two should be enough for basic tweaking :)
