Daryn Sharp updated HADOOP-8906:
--------------------------------
Attachment: HADOOP-8906.patch
A Path from Path.CUR_DIR is internally an empty string, which the Path ctors
won't allow so had to ensure to use Path.CUR_DIR when the path is empty.
Fixed issue where globbing failed unexpectedly when the starting directory
doesn't exist - ex. relative path and home dir doesn't exist. Added exception
handler. Had to pre-compute if globs are present before attempting lookup in
order to return the correct value.
> paths with multiple globs are unreliable

> Let's say we have have a structure of "$date/$user/stuff/file". Multiple
> globs are unreliable unless every directory in the structure exists.
> These work:
> date*/user
> date*/user/stuff
> date*/user/stuff/file
> These fail:
> date*/user/*
> date*/user/*/*
> date*/user/stu*
> date*/user/stu*/*
> date*/user/stu*/file
> date*/user/stuff/*
> date*/user/stuff/f*
