>
> Key: PIG-2495
> URL: https://issues.apache.org/jira/browse/PIG-2495
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.9.1, 0.9.2
> Environment: HBase 0.90.3, Hadoop 0.20-append
> Reporter: Kevin Lion
> Assignee: Kevin Lion
> Fix For: 0.9.2

> To increase performance of my computation, I would like to use a merge join
> between two tables to increase speed computation but it produces an error.
> Here is the script:
> {noformat}
> start_sessions = LOAD 'hbase://startSession.bea000000.dev.ubithere.com' USING
> org.apache.pig.backend.hadoop.hbase.HBaseStorage('meta:infoid meta:imei
> meta:timestamp', '-loadKey') AS (sid:chararray, infoid:chararray,
> imei:chararray, start:long);
> end_sessions = LOAD 'hbase://endSession.bea000000.dev.ubithere.com' USING
> org.apache.pig.backend.hadoop.hbase.HBaseStorage('meta:timestamp meta:locid',
> '-loadKey') AS (sid:chararray, end:long, locid:chararray);
> sessions = JOIN start_sessions BY sid, end_sessions BY sid USING 'merge';
> STORE sessions INTO 'sessionsTest' USING PigStorage ('*');
