Subject [jira] [Commented] (HADOOP-8847) Change untar to use Java API instead of spawning tar process
Date Wed, 03 Oct 2012 11:10:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13468473#comment-13468473
] 

Steve Loughran commented on HADOOP-8847:
----------------------------------------

that code snippet shows that the dest dir perms are setup -but doesn't touch the contents
of the files itself. If someone needs x permissions on binaries there then there's a regression
risk here -which is what Robert sounds like he's going to hit

> 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.
