[Zebra] To support writing multiple Zebra tables through Pig
Key: PIG-1375
URL: https://issues.apache.org/jira/browse/PIG-1375
Project: Pig
Issue Type: New Feature
Affects Versions: 0.7.0
Reporter: Chao Wang
Assignee: Chao Wang
Fix For: 0.8.0
Attachments: PIG-1375.patch, PIG-1375.patch, PIG-1375.patch
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.

Thank Xuefu for the feedback.
Updated the patch to incorporate in comment 2 and 4.
For comment 1) The indentation change is only incidental to make some files
(impacted by this feature) to follow Zebra's tab policy - space of width two.
For comment 3) The flag idea needs to be justified by further performance
profiling work. The check here should be trivial compared with other operations
such as generateKey() and insert().
