Allen Wittenauer commented on HADOOP-11764:
-------------------------------------------
bq. I'm not sure it's a good idea. Configuration is used by a couple of other
projects in Hadoop ecosystem. It's likely to be a more risky change and expose
something unnecessary to other projects.
Fine. What about the service code? There are lots and lots of options here...
But Configuration should probably populate the system properties when it reads
in configs though....
bq. I'm not sure if I understand your point here, but "increasing line length"
doesn't sound like something that will almost certainly break some users at
some point in time, unless those some users are very special to be CLI length
sensitive.
You've just described every version of Unix ever. It's called ARG_MAX and it
becomes a real problem at extremely long lengths. It's something we need to be
vigilant about to make sure it doesn't grow to big. With shell profiles, it's
going to get even bigger as 3rd parties add more content...

> /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.
