Subject Re: Phoenix Pig integration
Date Mon, 10 Aug 2015 08:21:42 GMT
Here are the steps -

-- Phoenix version - 4.2.2
-- CDH -- 5.3

-- SQLLINE
CREATE TABLE HIRES_SALTED( CLIENTID INTEGER NOT NULL, EMPID INTEGER NOT
NULL, NAME VARCHAR CONSTRAINT pk PRIMARY KEY(CLIENTID,EMPID))
SALT_BUCKETS=2;

UPSERT INTO HIRES_SALTED VALUES(10,100,'ABC');
UPSERT INTO HIRES_SALTED VALUES(11,101,'XYZ');

-- PIG
register '/opt/phoenix-4.2.2-bin/phoenix-pig-4.2.2.jar';
register '/opt/phoenix-4.2.2-bin/phoenix-4.2.2-client.jar';

raw = LOAD 'hbase://table/HIRES_SALTED' USING
org.apache.phoenix.pig.PhoenixHBaseLoader('localhost');
dump raw

================================================================================

If we create table with SALT everything works without any issue.

Can anyone please help ?


Many Thanks
