-----------------------------------
Summary: Users should not need to setup TezGroupedInputFormat to
enable grouping
Key: TEZ-1386
URL: https://issues.apache.org/jira/browse/TEZ-1386
Project: Apache Tez
Issue Type: Improvement
Reporter: Siddharth Seth
Assignee: Siddharth Seth
To enable grouping via Tez, users should not need to change the underlying
InputFormat. A simple enable / disable option should be sufficient.
MRInputConfigurer does this.
Many of the methods in MRHelpers, however, require an InputFormat to be
specified. The main objective of this JIRA is to get rid of this requirement in
favor of a simple enableGrouping flag.
Marking this as a blocker for TEZ-1347, since it should simplify the set of
APIs required. Also, making all the changes in TEZ-1347 would just lead to a
very large patch.
