[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: 0.8.0
Reporter: Chao Wang
Assignee: Chao Wang
Fix For: 0.8.0
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.
