Robert Kanter commented on HADOOP-13254:
----------------------------------------
I wasn't meaning to overly complicate things here. My concern was that if
someone went and made their own plugin, that we don't want them to cause
problems in the NM. If we're going to restrict the plugins to only
Hadoop-supplied ones, which it looks like we are (re-looking at the code, I see
that we have Private audience and Unstable on the {{DiskValidator}} interface),
then I think it's fine to not worry about Threads, being super defensive, and
those sorts of things for now.
Given that, I'm +1 on the 008 patch. I'll commit this tomorrow if nobody has
any other comments.
