Hi Vijay
Is your hbase working independently without any issues. I mean, are you
able to insert data into hbase tables without using hive integration?
Was the same error message thrown when you directly provided hbase.master
instead of zookeeper quorum?

Re: HBASE and HIVE Integration
Hi Vijay You have provided the hbase master directly. (It is fine for single node hbase installation). But still can you try providing the zookeeper quorum instead. If that doesn't work as well , please post the error log from the mapreduce tasks? Just go the jobtracker page and drill down on the corresponding job to get the failed tasks. From each failed tasks you can get the error logs. http://0.0.0.0:50030/jobdetails.jsp?jobid=job_201207250246_0005 Regards Bejoy KS From: vijay shinde vijaysanj...@gmail.com To: user@hive.apache.org; bejoy...@yahoo.com Sent: Wednesday, July 25, 2012 6:58 PM Subject: Re: HBASE and HIVE Integration Hi Bejoy, Thanks for quick reply.

Hi Bejoy, I made some changes as per your suggetion.

But still can you try providing the zookeeper quorum instead. If that doesn't work as well , please post the error log from the mapreduce tasks? Just go the jobtracker page and drill down on the corresponding job to get the failed tasks. From each failed tasks you can get the error logs. http://0.0.0.0:50030/jobdetails.jsp?jobid=job_201207250246_0005 Regards Bejoy KS -- *From:* vijay shinde vijaysanj...@gmail.com *To:* user@hive.apache.org; bejoy...@yahoo.com *Sent:* Wednesday, July 25, 2012 6:58 PM *Subject:* Re: HBASE and HIVE Integration Hi Bejoy, Thanks for quick reply.
