Subject [jira] [Commented] (YARN-2562) ContainerId@toString() is unreadable for epoch >0 after YARN-2182
Date Tue, 23 Sep 2014 22:02:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2562?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14145524#comment-14145524

Tsuyoshi OZAWA commented on YARN-2562:
--------------------------------------

Thanks for the comments and suggestion, Jian and Vinod.

[~jianhe] OK, I'll add the comment in a next patch.

my fourth preference is to have something like container_1410901177871_0001_01_000005_e17,
the first three preferences are what I proposed above

[~vinodkv] I agree with changing the verbose prefix to "e". I think {{container_1410901177871_0001_01_000005_e17}}
looks best way - it's human readable, easy to implement, and can be parsed with old ConverterUtil.
I'll update a patch based on the approach.

> ContainerID string format is unreadable for RMs that restarted at least once (epoch >
0) after YARN-2182. For e.g, container_1410901177871_0001_01_000005_17.
