> [~xyao] discovered that when running {{ozone fs -mkdir -p ofs://om/vol1/}}, the command would fail in {{getFileStatus}} (before reaching {{createDirectory()}}) in Hadoop common code:
> {code:bash}
> 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
> {code}
> And we discovered with debugger attached that the root cause is that {{getFileStatus()}} is not behaving as expected.
> Suggested workaround: Patch existing OFS code, throw proper exception in {{getBucket()}} code to make Hadoop common happy.
