Hello list,

   I am trying to use Hbase and Hive together and I am able to create
tables in Hbase using Hive..But while inserting I am facing the
following error -

INSERT OVERWRITE TABLE table1 SELECT * FROM pokes WHERE foo=2;
Total MapReduce jobs = 1
Launching Job 1 out of 1
Number of reduce tasks is set to 0 since there's no reduce operator

I am using Hadoop-.20.205.0, Hbase-0.90.4 and Hive-0.7.1..Initially I
was facing problems while creating table also, so I copied Hbase jars
into Hive/lib and I was able to create the tables..Do I need any such
things for insertion as well???
