Bikas Saha commented on TEZ-2421: --------------------------------- At this point, I will need to investigate the recovery logic further for a workaround/fix. Since this issue does not always happen, I suggest removing it as a blocker for 0.7.0 to enable the new API's to be consumed by other projects. We can follow up immediately with 0.7.1 with a specific fix for this issue. > Deadlock in AM because attempt and vertex locking each other out > ---------------------------------------------------------------- > > Key: TEZ-2421 > URL: https://issues.apache.org/jira/browse/TEZ-2421 > Project: Apache Tez > Issue Type: Bug > Reporter: Bikas Saha > Assignee: Bikas Saha > Priority: Blocker > Attachments: TEZ-2421.1.patch, TEZ-2421.2.patch, TEZ-2421.3.patch > > > Ideally locks should be taken one way - either going down or up.
