---------------------------------------
Summary: Work with TEZ-668 which allows starting and closing of
inputs and outputs
Key: PIG-3767
URL: https://issues.apache.org/jira/browse/PIG-3767
Project: Pig
Issue Type: Sub-task
Reporter: Rohini Palaniswamy
Assignee: Rohini Palaniswamy
Fix For: tez-branch
>From [~bikassaha]:
https://issues.apache.org/jira/browse/TEZ-668 is a breaking change in TEZ trunk
This adds a start method to the Input/Output and the processor is expected to
call input.start()/output.start() for the input/output to actually start
fetching/writing data. After this get committed, Hive and Pig Processors need
to call start() on the input/output that they want to start. The processors may
decide to not call start for an input they do not want to read (e.g. data
already in ObjectRegistry) or they may choose to stagger the inputs in a
certain order based on memory or processing requirements.
