Subject [jira] [Commented] (HADOOP-8873) Port HADOOP-8175 (Add mkdir -p flag) to branch-1
Date Wed, 03 Oct 2012 13:30:08 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8873?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13468554#comment-13468554
] 

Daryn Sharp commented on HADOOP-8873:
-------------------------------------

The only difference other than parent creation is that -p doesn't fail if the directory already
exists whereas a normal mkdir should.  If 1.x mkdir doesn't fail on existence, then -p can
be a no-op.

> Per HADOOP-8551 let's port the mkdir -p option to branch-1 for a 1.x release to help
users transition to the new shell behavior. In Hadoop 2.x mkdir currently requires the -p
option to create parent directories but a program that specifies it won't work on 1.x since
it doesn't support this option.
