The test does not completely delete znodes under /zkTest

After I ran asynchronous test, I found that there is /zkTest znode and many child znodes.
It would be nice to delete the /zkTest node after the test finishes.

In case someone else is also stuck like I was when deleting the zkTest node (rmr from zkCli).
The delete fails because jute.maxbuffer default is not sufficient.

Run CLIENT_JVMFLAGS="-Djute.maxbuffer=10485760" ./zkCli.sh and then execute rmr /zkTest
You may have to further increase the maxbuffer if delete is partial.
