Sreekanth Ramakrishnan commented on HADOOP-4238:
------------------------------------------------
Fixing the column with alignment can break the existing script which might
dependent on the tab delimited values which are currently being generated by
the script. Making any changes or making it fixed with table would mean
rewriting parsing logic which scripts might currently use today. Plus this
would mean that we would have to make assumptions on length of the scheduling
information on a particular job or other attributes which are currently being
displayed.
> [mapred] Unavailable schedulingInfo in "hadoop list [all]" output should be

> print anything. This, combined with the fact that the columns are not aligned
> properly, makes it difficult to comprehend the output.
