Hi，Vijay
You need to add zookeeper.jar to the hive-site.xml
<name>hive.aux.jars.path</name>
<value>file:///usr/lib/hive/lib/hive-hbase-handler-0.7.1-cdh3u4.jar,file:///usr/lib/hive/lib/hbase-0.92.jar,file:///usr/lib/hive/lib/zookeeper-3.4.3.jar,file:///usr/lib/hive/lib/hive-contrib-0.7.1-cdh3u4.jar,
file:///usr/lib/hive/lib/ zookeeper-3.4.3.jar </value>
</property>
<name>hbase.zookeeper.quorum</name>
<value>localhost</value>
</property>
Regards
Ransom

Hi Bejoy,
I made some changes as per your suggetion.
Here is the error from the
http://0.0.0.0:50030/jobdetails.jsp?jobid=job_201207251858_0004 Job:

I went ahead and updated the hadoop-env.sh file and set the class path for
hbase and zookeeper as follows:
# Extra Java CLASSPATH elements. Optional.
export
HADOOP_CLASSPATH="/usr/lib/hive/lib/hbase-0.92.jar:/usr/lib/hive/lib/zookeeper-3.4.3.jar:$HADOOP_CLASSPATH"

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.

Hi Vijay
Can you share more details like
The CDH Version/Hive version you are using
Steps you followed for hive hbase integration with the values you set
The DDL used for hive hbase integration
The actual error from failed map reduce task

Subject: HBASE and HIVE Integration
I am facing issue while executing HIVE queries on HBASE-HIVE integration.
I followed the wiki hbase-hive integration
https://cwiki.apache.org/Hive/hbaseintegration.html
I have already passed all the required jars for auxpath in hive-site.xml file.
I am using Cloudera CDH demo VM.. Any help would be highly appreciated
