Subject Exception causing close of session
Date Thu, 26 Aug 2010 23:03:19 GMT
Hi,
zookeeper-3.2.2 is used out of HBase 0.20.5

Linux sjc1-.com 2.6.18-92.el5 #1 SMP Tue Jun 10 18:51:06 EDT 2008 x86_64
x86_64 x86_64 GNU/Linux

In hbase-hadoop-zookeeper-sjc1-cml-grid00.log, I see a lot of the following:

2010-08-26 22:58:01,930 INFO org.apache.zookeeper.server.NIOServerCnxn:

2010-08-26 22:58:02,097 INFO org.apache.zookeeper.server.NIOServerCnxn:

If you can shed some thought on root cause, that would be great.
