Steve Loughran commented on HADOOP-8847:
----------------------------------------
correction -you aren't using any Sun Java APIs -I misread that. Commons
compress 1.1+ claims to handle Posix [
https://issues.apache.org/jira/browse/COMPRESS-110 ]; Ant's handled LFNs for a
long time.
All that is needed is tests to verify that LFNs are handled.
Ignoring file permissions may be backwards incompatible, but I'm not sure if
anyone was actually using it. It's probably best to tag it as such just to
avoid surprises.

> 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.
