Sunil G commented on YARN-2301:
-------------------------------
This will be really useful enhancement.
I have a concern here.
bq. yarn container -list <appId|appAttemptId> <additional opts>
* *list* with *<additional opts>* comes after the variable input from user
(appId|appAttemptId).
And <additional opts> is only for one of the type named *appId*. May be it may
confuse user also, like which sub option needs the <additional opts>.
I feel may be we can have a new command itself for listing application
container.
A suggestion is:
{noformat}
yarn container -list-appid <appId> <additional opts>
yarn container -list-appattemptid <appAttemptId>
{noformat}
OR
{noformat}
yarn application -list-containers <appId>
{noformat}
* I feel sequential checks with ConverterUtils.toApplicationID and
ConverterUtils.toApplicationAttemptId has to be done to know whether input is
appId|appAttemptId.
So rediercting to my point 1, if seperate command is there, may be it can be
handled in a better way from applicationCLI (rather than handling specific
types of exceptions).
Please share your thoughts

> Labels: usability
>
> While running yarn container -list <Application Attempt ID> command, some
> observations:
> 1) the scheme (e.g. http/https ) before LOG-URL is missing
> 2) the start-time is printed as milli seconds (e.g. 1405540544844). Better to
> print as time format.
> 3) finish-time is 0 if container is not yet finished. May be "N/A"
> 4) May have an option to run as yarn container -list <appId> OR yarn
> application -list-containers <appId> also.
> As attempt Id is not shown on console, this is easier for user to just copy
> the appId and run it, may also be useful for container-preserving AM
> restart.
