…Utils.unpack ### What changes were proposed in this pull request? This PR proposes to use `FileUtil.unTarUsingJava` that is a Java implementation for un-tar `.tar` files. `unTarUsingJava` is not public but it exists in all Hadoop versions from 2.1+, see HADOOP-9264. The security issue reproduction requires a non-Windows platform, and a non-gzipped TAR archive file name (contents don't matter). ### Why are the changes needed? There is a risk for arbitrary shell command injection via `Utils.unpack` when the filename is controlled by a malicious user. This is due to an issue in Hadoop's `unTar`, that is not properly escaping the filename before passing to a shell command:https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileUtil.java#L904 ### Does this PR introduce _any_ user-facing change? Yes, it prevents a security issue that, previously, allowed users to execute arbitrary shall command. ### How was this patch tested? Manually tested in local, and existing test cases should cover. Closes apache#35946 from HyukjinKwon/SPARK-38631. Authored-by: Hyukjin Kwon <gurwls223@apache.org> Signed-off-by: Hyukjin Kwon <gurwls223@apache.org> (cherry picked from commit 057c051) Signed-off-by: Hyukjin Kwon <gurwls223@apache.org>
