Karthik Kambatla commented on HADOOP-11878:
-------------------------------------------
As others have mentioned here, we should figure out why the directory is null
and fix the root cause in Yarn. Can we use YARN-3793 to do that? Please feel
free to take it up.
That said, it would be nice to make the exception easier to decipher and
document it at every place FileContext#fixRelativePart is used. And, I believe
checkNotNull is more appropriate than checkArgument.
> NPE in FileContext.java # fixRelativePart(Path p)
