---------------------------------

             Summary: ArrayIndexOutOfBoundsException happens in ScatterGatherEdgeManager after DAG recovery
                 Key: TEZ-3416
                 URL: https://issues.apache.org/jira/browse/TEZ-3416
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Zhiyuan Yang
            Assignee: Zhiyuan Yang
         Attachments: applog

This happened in Hive on Tez. The query is select count(*) from f as a, f as b. When I manually killed AM, all vertices except the one join the data finished reconfiguration. After recovery, DAG failed with ArrayIndexOutOfBoundsException in ScatterGatherEdgeManager of the counting vertex. It doesn't happen every time.
