Jason Lowe commented on HADOOP-8906:
------------------------------------
bq. The current behavior does seem kind of... odd.
Agreed it does some odd things, but actually the example you gave is exactly
what I would expect since UN*X shells do the same thing. The wildcard expands
to match 'a' and then the 'a' directory is passed as an argument to the 'ls'
command.
{noformat}
$ ls ./*
ls: cannot access ./*: No such file or directory
$ mkdir -p a/b/c
$ ls ./*
b
{noformat}
> 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*
