>                 Key: YARN-3310
>                 URL: https://issues.apache.org/jira/browse/YARN-3310
>             Project: Hadoop YARN
>          Issue Type: Improvement
>            Reporter: Ramya Sunil
>            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
