Description

Consider the following:
A and B should be the same (with different order, of course).

/*
in hbase shell:

create 'pigtest', 'pig'
put 'pigtest' , '1', 'pig:name', 'A'
put 'pigtest' , '1', 'pig:has_legs', 'true'
put 'pigtest' , '1', 'pig:has_ribs', 'true'
*/
A = LOAD 'hbase://pigtest' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('pig:name pig:has*') AS (name:chararray,parts);

B = LOAD 'hbase://pigtest' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('pig:has* pig:name') AS (parts,name:chararray);

dump A;
dump B;

This is due to a bug in setLocation and initScan.
For A

1. scan.addColumn(pig,name); // for 'pig:name'
2. scan.addFamily(pig); // for the 'pig:has*'

So that's silently right.

But for B

1. scan.addFamily(pig)
2. scan.addColumn(pig,name)

will override the first call to addFamily, because you cannot mix them on the same family.
