Allen Wittenauer resolved HADOOP-11137.
---------------------------------------
Resolution: Won't Fix
> put up guard rails around pid and log file handling
> ---------------------------------------------------
>
> Key: HADOOP-11137
> URL: https://issues.apache.org/jira/browse/HADOOP-11137
> Project: Hadoop Common
> Issue Type: Improvement
> Components: scripts, security
> Reporter: Allen Wittenauer
> Priority: Major
> Labels: newbie, scripts, security
>
> We should do a better job of protecting against symlink attacks in the pid
> and log file handling code:
> a) Change the default location to have a user or id.str component
> b) Check to make sure a pid file is actually a pid file (single line, nothing
> but numbers)
> ... maybe other stuff?
