Subject [jira] [Commented] (ACCUMULO-2111) Allow AccumuloClassLoader to use shell globbing
Date Mon, 30 Dec 2013 22:43:50 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2111?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13859145#comment-13859145

Josh Elser commented on ACCUMULO-2111:
--------------------------------------

That's fine by me. I've had it in the back of my mind to come up with a good way to generate
some more "visually consumable" configuration documentation from our Property class. But that's
neither here nor there.

>             Project: Accumulo
>          Issue Type: Improvement
>          Components: start

> Right now, the classpath parsing for hte AccumuloClassLoader supports
> * non-file URLs
> * paths to a jar file
> * paths to a directory
> * paths with regex matching at the file level
> This behavior is undocumented and incompatible with the output of other ecosystem tools,
most importantly the "[hadoop classpath|http://hadoop.apache.org/docs/r1.0.4/commands_manual.html#classpath]"
command. that command may use shell globbing (depending on the hadoop distro).
> Proposed solution:
> * abstract the matching behavior
> * add matching by shell globbing
> * add a flag that determines if regex, globbing, or both (regex falling back to globbing)
is used
> the flag should default to regex to maintain current out-of-the-box behavior.
