Subject [jira] [Commented] (HADOOP-7521) bintar created tarball should use a common directory for prefix
Date Fri, 05 Aug 2011 22:07:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13080257#comment-13080257
] 

Milind Bhandarkar commented on HADOOP-7521:
-------------------------------------------

Eric, From the link you mentioned, first para (I have highlighted the "or some other existing
dir" part):

A tarbomb, also sometimes written as tar bomb, is a tarball whose contents appear to explode
into the current directory *or some other existing directory* containing a large number of
items when untarred rather than into a new directory created by the tarball specifically for
such contents.

As a unix user for the last 25 years, my expectation would be that each untar creates a new
directory under $cwd rather than unpacking into an existing directory.

So, I am -1 on this.

> The binary tarball contains the directory structure like:
> {noformat}
> hadoop-common-0.23.0-SNAPSHOT-bin/bin
>                                  /etc/hadoop
>                                  /libexec
>                                  /sbin
>                                  /share/hadoop/common
> {noformat}
> It would be nice to rename the prefix directory to a common directory where it is common
to all Hadoop stack software.  Therefore, user can untar hbase, hadoop, zookeeper, pig, hive
all into the same location and run from the top level directory without manually renaming
them to the same directory again.
> By default the prefix directory can be /usr.  Hence, it could merge with the base OS.
