Description

Since version 0.96 HBase introduced namespace support.
Apace Pig has recently updated the HBase dependency to 0.98.12 (PIG-4544)

Currently there's no way to specify the namespace for a table.
I suggest to implement it is using a '-namespace' option.

copy = STORE raw INTO 'hbase://SampleTableCopy'
       USING org.apache.pig.backend.hadoop.hbase.HBaseStorage(
       'info:first_name info:last_name friends:* info:*','-namespace SampleNamespace');

We can't use the namespace in the hbase path as it will break the uri validation : 'hbase://SampleNamespace:SampleTableCopy'

The patch is available. I will look to extend the unittest for the namespace option.

Please review my changes and let me know if I can help with something.

Kind regards,

Andi
