-Re: Storing tuple into HBaseStorage

You should be able to use a Pig map to do this. Use the column name as the
key in the map and the value as the value. You should be able to use the
builtin TOMAP function to generate the map (
http://pig.apache.org/docs/r0.11.0/func.html#tomap). The HBaseStorage
documentation gives an example of storing a map using friends:* and info:*
as the column families.
copy = STORE raw INTO 'hbase://SampleTableCopy'
'info:first_name info:last_name friends:* info:*');
