pig with Hbase
Mohit Anchlia 2012-08-06, 18:31
I am trying to read records from HBase using HBaseStorage. When I execute
simple load I get this error. I think I am missing some property, but I am
running pig on the cluster where hadoop and hbase is there.

I also have HBASE_HOME set:

# env|grep HBASE
HBASE_HOME=/opt/mapr/hbase/hbase-0.90.6/
