> MR-279: Log info about the location of dist cache
> -------------------------------------------------
>                 Key: YARN-3310
>                 URL: https://issues.apache.org/jira/browse/YARN-3310
>             Project: Hadoop YARN
>          Issue Type: Improvement
>            Reporter: Ramya Sunil
>            Assignee: Siddharth Seth
>            Priority: Minor
> Currently, there is no log info available about the actual location of the 
> file/archive in dist cache being used by the task except for the "ln" command 
> in task.sh. We need to log this information to help in debugging esp in those 
> cases where there are more than one archive with the same name. 
> In 0.20.x, in task logs, one could find log info such as the following:
> INFO org.apache.hadoop.mapred.TaskRunner: Creating symlink: <distcache 
> location>/archive <- <mapred.local.dir>/archive
