Hi,
Thanks for the reply. I have properties as below
<property>
<name>hbase.regionserver.lease.period</name>
<value>900000</value>
</property>
<property>
<name>hbase.rpc.timeout</name>
<value>900000>/value>
</property>
Correct me If I am wrong.
I know hbase.regionserver.lease.period, which says how long a scanner
lives between calls to scanner.next().
As far as I understand when scanner.next() is called it will fetch no
of rows as in *hbase.client.scanner.caching. *When this fetching
process takes more than lease period it will close the scanner object.
so this exception occuring?
Thanks,
Rajeshkumar J
