Hi there,
I am a new guy learning storm by following this tutorial, Running a
Multi-Node Storm Cluster
<http://www.michael-noll.com/tutorials/running-multi-node-storm-cluster/#java-6>.
My configuration is almost the same as this tutorial posted except that
the java version in my machine is Oracle JDK 6 and storm version is 0.9.3.
Everything goes quite well before I tried to start the slave node. the
nimbus daemon and ui have been successfully initialized and the
configuration of nimbus and Zookeeper could be seen through a browser. But
when it comes to starting a slave node, a strange error occurred. the
error message is pasted as follows:
2015-01-28T23:19:34.201+0000 b.s.d.supervisor [ERROR] Error on
initialization of server mk-supervisor

The most tricky part is that sometimes this error won't be triggered, and
all I have done is just restarting the node or recover it from a snapshot.
But this operation cannot guarantee the successful initialization of the
slave. Can someone help me please, I have been stuck on it for several
days. Thank you.
