Steve Loughran commented on HADOOP-13797:
-----------------------------------------
Do we introduce any security risk by doing this? That a malicious version of ls
has got onto the path?
Given we did the change for bin/bash, I doubt there is any risk —just need to
be thorough.
> Remove hardcoded absolute path for ls
