> In Zebra, we already have multiple outputs support for map/reduce.  But we do not support
this feature if users use Zebra through Pig.
> This jira is to address this issue. We plan to support writing to multiple output tables
through Pig as well.
> We propose to support the following Pig store statements with multiple outputs:
> store relation into 'loc1,loc2,loc3....' using org.apache.hadoop.zebra.pig.TableStorer('storagehint_string',
> 'complete name of your custom partition class', 'some arguments to partition class');
/* if certain partition class arguments is needed */
> store relation into 'loc1,loc2,loc3....' using org.apache.hadoop.zebra.pig.TableStorer('storagehint_string',
> 'complete name of your custom partition class'); /* if no partition class arguments is
needed */
> Note that users need to specify up to three arguments - storage hint string, complete
name of partition class and partition class arguments string.
