Siddharth Seth commented on TEZ-2426: ------------------------------------- Longer term - 0.8, may be worthwhile to rework some of this, along with protocol changes. > Task input not complete before sending Task completed event > ----------------------------------------------------------- > > Key: TEZ-2426 > URL: https://issues.apache.org/jira/browse/TEZ-2426 > Project: Apache Tez > Issue Type: Bug > Reporter: Bikas Saha > Priority: Critical > Attachments: am.log, container.log > > > Sequence of events > 1) Task A starts in a container > 2) Task A complete event comes to AM > 3) Task B starts in the same container > 4) Task A's input calls some method on its context. Crashes with NPE > 5) The crash sends an input failed event for Task A to the AM > 6) Task A state machine crashes saying cannot handle failed after success > In some cases, it could be that status update event is also sent after > completion, though not sure if its related to the failed event being sent. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
