-----------------------------------
Assignee: madhukara phatak (was: Eli Collins)
javadoc warnings are unrelated.
+1
Nit: the indenting on the new line is off, see the surrounding code, and the
new test needs a newline before it, I'll fix these before committing, for
future patches please indent according to the convention.
Thanks for contributing!

> DiskChecker#checkDir fails if a directory can't be created, read, or written
> but does not fail if the directory exists and is not executable. This causes
> subsequent code to think the directory is OK but later fail due to an
> inability to access the directory (eg see MAPREDUCE-2921). I propose checkDir
> fails if the directory is not executable. Looking at the uses, this should be
> fine, I think it was ignored because checkDir is often used to create
> directories and it creates executable directories.
