["Harsh J (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-7795?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13153458#comment-13153458 ] 

Harsh J commented on HADOOP-7795:
---------------------------------

I wonder if we really need this. Given the type of data mostly stored on HDFS, how useful is it to provide an internal ability to print line numbers?

It could be done, perhaps a small bit sub-optimally, by external programs using the output of fs-shell's -cat today.
