Description

xyao discovered that when running ozone fs -mkdir -p ofs://om/vol1/ (only volume name is given, no bucket name or key path), the command would fail in getFileStatus (before reaching createDirectory()) in Hadoop common code:

bash-4.2$ ozone fs -mkdir -p ofs://om/vol1/
-mkdir: Bucket or Volume length is illegal, valid length is 3-63 characters

# Same w/o -p
bash-4.2$ ozone fs -mkdir ofs://om/vol1/
-mkdir: Bucket or Volume length is illegal, valid length is 3-63 characters

And we discovered with debugger attached that the root cause is that getFileStatus() is not behaving as expected.

Solution: Patch existing OFS code, throw proper exception in getBucket() code to make Hadoop common happy.
