Jonathan Eagles commented on YARN-2035:
---------------------------------------
In my scenario, the dir already exists and so I don't want to crash trying to
create an existing dir. The code you mentioned could be helpful for the first
time startup but it's a slightly different scenario I care about. Let me know
if you if we should handle that as part of this jira or separately.
