Daryn Sharp commented on HADOOP-8906:
-------------------------------------
There's more multi-glob bugginess. Given {{/file}}, and {{/dir/file}}:
# {{/\*/file}} will fail with a permission denied because it tries to treat
{{/file}} as a directory since it matches the first "*".
# Worse yet, {{/\*/file\*}} will return BOTH {{/file}} and {{/dir/file}}!
> paths with multiple globs are unreliable

> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 0.23.0, 2.0.0-alpha, 3.0.0
> Reporter: Daryn Sharp
> Priority: Critical
>
> 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*
