----------------------------------------

I can make the change but i dont have the HW to test it out. Let me know. Also
been debating this.. do we want different default env vars for server and
client? If they are different you can have the same config on the client and
the server machines.
> zookeeper should set a default value for SERVER_JVMFLAGS and CLIENT_JVMFLAGS
> so that memory usage is controlled
