Re: flume+hbase+zookeeper, can't hang on to zookeeper session
My 2 cents:

In past when i have used OpenJDK, i ran into a DNS resolution trouble with
Hadoop/HBase. The problem was resolved when i started using Sun Jdk. I
would suggest you to try the preferred version of Sun Java 1.6. You can
find this info on HBase website. It's worth a try although i am not sure
that this is the problem.

HTH,
Anil Gupta
