Has grown quite a bit. Changes. - unassignable containers will not be held on to. - new callback to apps to indicate container release - so that the app can be told about delayed container releases. - App callbacks are now handled by a separate Executor - since some calls need to be made from deep inside a call stack. That contributes a big chunk towards the size increase. - TEZ-356 should be resolved - using assignedContaienrs as a repository for containers which, at some point, have run a task, but haven't been released yet. - A delay value of 0 effectively disables putting anything into the delay queue. - Couple new unit tests. > Support delayed scheduling for re-used containers > ------------------------------------------------- > > Key: TEZ-344 > URL: https://issues.apache.org/jira/browse/TEZ-344 > Project: Apache Tez > Issue Type: Improvement > Reporter: Siddharth Seth > Assignee: Siddharth Seth > Labels: TEZ-0.2.0 > Attachments: TEZ-344.2.txt, TEZ-344.wip.txt > > > This, for now, is primarily to help with testing of Tez on clusters. > Would have to go in with a warning since this could cause jobs to hang / run for a long time. > Longer term, this can be enhanced to set limits on how long to wait before assigning non-local tasks. -- This message is automatically generated by JIRA.
