---------------------------------
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.
