Hi All
I basically have a thread pool which has the task of pushing data into
HBASE. However, it is seen that wheneever the data rate is very high, which
means that i have many records to be pushed into hbase at one time. I get
the following exception which is thrown by the put api of hbase client.
org.apache.zookeeper.KeeperException$SessionExpiredException:

PS : I am using the Htablepool to manage the htable connections. I did
increase the zookeeper.session.timeout in the hbase-site.xml but that is not
helping either
