Allen Wittenauer commented on HADOOP-11764:
-------------------------------------------

[~vinodkv], this is the JIRA we were discussing at Hadoop Summit.  Please take 
a look at it.

... and just so it's official, I'm very much a (binding) -1 on pushing this 
into an environment variable until it can proven otherwise that this can't be 
handled via *-site.xml.

> Hadoop should have the option to use directory other than tmp for extracting 
> and loading leveldbjni

> /tmp can be  required to be noexec in many environments. This causes a 
> problem when  nodemanager tries to load the leveldbjni library which can get 
> unpacked and executed from /tmp.
