             Summary: Add an option to allow small splits early on in TezSplitGrouper
                 Key: TEZ-2978
                 URL: https://issues.apache.org/jira/browse/TEZ-2978
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Siddharth Seth


In certain cases, allowing the last few splits to be 'small' - smaller than the requested size is beneficial, and can end up creating fewer splits. Also this results in all splits having some form of locality information.
