[jira] [Created] (HDFS-5173) prettier dfsadmin -listCachePools output

Colin Patrick McCabe created HDFS-5173:
------------------------------------------

             Summary: prettier dfsadmin -listCachePools output
                 Key: HDFS-5173
                 URL: https://issues.apache.org/jira/browse/HDFS-5173
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: HDFS-4949
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe
            Priority: Minor


We can make the output of -listCachePools prettier by doing the same kinds of things as ls -l does.  We probably need to find (or write) some code to properly line up columns to avoid ragged-looking output.  Finally, column headers will be necessary here to let people know what they're looking at.  Ideally, we'd implement a format-string type argument like {{--format=}} for ls.
