----------------------------
Summary: Shuffle split array when size-based sorting is turned off
Key: TEZ-3552
URL: https://issues.apache.org/jira/browse/TEZ-3552
Project: Apache Tez
Issue Type: Improvement
Reporter: Ming Ma
TEZ-3430 adds the functionality to skip size-based split sorting to help with
job runtime. During further testing, the original split array for certain
inputs before sorting aren't randomly distributed in size. So when the spit
sorting is turned off, we should shuffle the split instead of doing nothing.
That will make the size distribution more even.
