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.
