[jira] [Updated] (TEZ-3193) Deadlock in AM during task commit request

     [ https://issues.apache.org/jira/browse/TEZ-3193?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jason Lowe updated TEZ-3193:
----------------------------
    Attachment: TEZ-3193-branch-0.7.001.patch

I'll work on the branch-0.7 patch.  In the meantime, here's the patch we applied to our internal Tez 0.7 version to work around the deadlock if that proves desirable for unblocking the 0.7 release.
