Subject Re: Pig - unable to read a Phoenix Table
Date Thu, 09 Jul 2015 16:57:06 GMT
Hi Durga,
   Please refer the table name as below in the LOAD.

s = load 'hbase://table/ndm_17.table1/' using org.apache.phoenix.pig.
PhoenixHBaseLoader('regionserver');

I am also hoping the 'regionserver' mentioned above is the zookeeper
quorum.

Regards
Ravi
