Subject [jira] [Commented] (HADOOP-13510) "hadoop fs -getmerge" docs, .../dir does not work, .../dir/* works.

    [ https://issues.apache.org/jira/browse/HADOOP-13510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15426502#comment-15426502

Rushabh S Shah commented on HADOOP-13510:
-----------------------------------------

The following command works for me.
I am running hadoop 2.7 with some internal fixes.
But none of the fixes are related to getmerge command.
{noformat}
hadoop fs -getmerge -nl /user/rushabhs/tmp1 /tmp/merge.java
{noformat}
May be if you can attach all the files in src folder (or a subset of the files which are enough
to reproduce this failure) then I can try running the command with that files and check whether
I encounter the bug.
But according to me it should work just fine.
Correct me if I am missing something here.
