Subject Sqoop import to HBase failing - timeout
Date Tue, 03 Sep 2013 13:19:38 GMT
Hi,

I'm executing a simple Sqoop import from an RDBMS to stand-alone HBase. Only two of thousands
of records are getting inserted. When I checked the hbase log :

2013-09-03 23:15:36,843 INFO org.apache.zookeeper.server.NIOServerCnxnFactory: Accepted socket

What is causing the connection closure? Do I need to increase the time-out somewhere?
