Rajesh Balamohan created TEZ-4216: ------------------------------------- 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
