Subject EndOfStreamException: Unable to read additional data from client
Date Wed, 17 Jul 2013 01:08:58 GMT
I have large amount of hbase data in my tables, which is splitted into 19
region servers. I am running map-reduce job on this table for processing. I
am running 11 node hadoop cluster, 11 region servers, and 3 zookeeper
instances. Everything seems to work fine and I can access hbase data using
shell. But when I run map-reduce job on this cluster, I get following
exceptions in zookeeper log.

2013-07-16 20:56:59,034 WARN org.apache.zookeeper.server.NIOServerCnxn:

Shall appreciate any help. My hbase version is 0.94.8 and I am running hbase
managed ZooKeeper.

Thanks
