------------------------------------
Summary: HBaseStorage returns empty maps when mixing wildcard-
with other columns
Key: PIG-3108
URL: https://issues.apache.org/jira/browse/PIG-3108
Project: Pig
Issue Type: Bug
Affects Versions: 0.10.0, 0.9.2, 0.9.1, 0.9.0, 0.11, 0.10.1, 0.12
Reporter: Christoph Bauer
Consider the following:
A and B should be the same (with different order, of course).
{code}
/*
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;
{code}
This is due to a bug in setLocation and initScan.
For _A_
# scan.addColumn(pig,name); // for 'pig:name'
# scan.addFamily(pig); // for the 'pig:has*'
So that's silently right.
But for _B_
# scan.addFamily(pig)
# scan.addColumn(pig,name)
will override the first call to addFamily, because you cannot mix them on the
same family.
