Anubhav Dhoot commented on HADOOP-11764:
----------------------------------------
bq. That's all putting it on the command line does, so why can't we do this in
Configuration?
[~aw] The solution demands writing to the environment and the proposed solution
does that. Isnt that better than adding code in each daemon to read from the
configuration and set it to the environment?
bq. If the temporal native lib is redirected to another dir, we also needs to
add that dir to JAVA_LIBRARY_PATH.
[~zjshen] This is an unrelated problem to the one this jira is solving. The
current jira is not solving native lib not found. Rather the jar cannot be
extracted and executed because of noexec permissions.
> 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.
