Subject [jira] [Commented] (HADOOP-8847) Change untar to use Java API instead of spawning tar process
Date Mon, 08 Oct 2012 20:20:03 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13471828#comment-13471828
] 

Robert Joseph Evans commented on HADOOP-8847:
---------------------------------------------

One thing to be aware of when porting this to trunk is that YARN is not doing the FileUtil.chmod.
 I don't think this will impact you for the windows port.  I just thought I should mention
it.

> Currently FileUtil.unTar() spawns tar utility to do the work. Tar may not be present
on all platforms by default eg. Windows. So changing this to use JAVA API's would help make
it more cross-platform. FileUtil.unZip() uses the same approach.
