Jason Lowe commented on HADOOP-8709:
------------------------------------
I don't think it's the job of globStatus to be used as a function to
distinguish between globbed paths and non-globbed paths based on return code.
There's a separate class, GlobFilter, which can be used to check for glob
patterns within a path with the added benefit that it doesn't require fs
operations.
Just discovered that FileContext has duplicated code and therefore the same
issues, javadoc inconsistencies and all.
> globStatus changed behavior from 0.20/1.x

> In 0.20 or 1.x, globStatus will return an empty array if the glob pattern
> does not match any files. After HADOOP-6201 it throws FileNotFoundException.
> The javadoc states it will return an empty array.
