Subject [jira] [Commented] (HADOOP-8847) Change untar to use Java API instead of spawning tar process
Date Fri, 12 Oct 2012 21:51:03 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13475389#comment-13475389
] 

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

Bikas -is there any reason to not make the {{close()}} operation in {{unpackEntries()}} part
of the try/finally logic? Other than that it looks good to be -the {{Shell.WINDOWS}} checks
ensure that the Unix untars will be the existing shell commands and not break anything

> 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.
