Vinod Kumar Vavilapalli commented on YARN-2562: ----------------------------------------------- How about {{container_e17_1410901177871_0001_01_000005}}? A number at the end for me always pointed to the container-id. We also don't need to be verbose with "epoch". And we can still parse it in a backwards compatible fashion. If nothing, my fourth preference is to have something like {{container_1410901177871_0001_01_000005_e17}}, the first three preferences are what I proposed above :P > ContainerId@toString() is unreadable for epoch >0 after YARN-2182 > ----------------------------------------------------------------- > > Key: YARN-2562 > URL: https://issues.apache.org/jira/browse/YARN-2562 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Vinod Kumar Vavilapalli > Assignee: Tsuyoshi OZAWA > Priority: Critical > Attachments: YARN-2562.1.patch > > > ContainerID string format is unreadable for RMs that restarted at least once > (epoch > 0) after YARN-2182.
