-------------------------------------
Summary: RLE check in MergeManager::finalMerge could be disabled
Key: TEZ-4216
URL: https://issues.apache.org/jira/browse/TEZ-4216
Project: Apache Tez
Issue Type: Improvement
Reporter: Rajesh Balamohan
[https://github.com/apache/tez/blob/master/tez-runtime-library/src/main/java/org/apache/tez/runtime/library/common/shuffle/orderedgrouped/MergeManager.java#L1319]
[https://github.com/apache/tez/blob/master/tez-runtime-library/src/main/java/org/apache/tez/runtime/library/common/sort/impl/TezMerger.java]
MergerManager's finalMerger() need not check for RLE. We could pass on the RLE
information from sorter via events. Until then, it would be good to turn off
RLE here.
