Getting RetriesExhaustedException while getting rows
Vidosh Sahu 2013-02-08, 08:57
Hi,

I have a pseudo-distributed setup of hbase/hadoop. I have 2 tables in hbase.

I have a scheduler which runs at some frequency. Scheduler kicks three
different mapper 1 by 1 (one the successful completion of the first one,
the next one starts).

When I ran it on lesser data it works fine, but in case of huge data it
throws the following exception -

org.apache.hadoop.hbase.client.RetriesExhaustedException: Trying to contact
region server null for region , row '*********************', but failed
after 10 attempts.
Exceptions:
java.io.IOException:
