Subject [jira] [Commented] (MAPREDUCE-5021) Add an addDirectoryToClassPath method DistributedCache
Date Fri, 22 Feb 2013 00:00:12 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5021?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13583693#comment-13583693

Alejandro Abdelnur commented on MAPREDUCE-5021:

This is equivalent to how java -classpath supports wildcards, i.e. {{lib/'*'}} to easily specify
all JARs in a directory. Regarding adding a new method, an alternative would be making the
existing addFileToClasspath() to detect if the provided path is a directory and then do the
addition of all JARs under it.

>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5021
>             Project: Hadoop Map/Reduce
>          Issue Type: Improvement
>          Components: client, distributed-cache
>    Affects Versions: 2.0.3-alpha
>            Reporter: Sandy Ryza
> As adding a directory of jars to the class path is a common use for the distributed cache
it would be easier on API consumers if they were able to call a method that would add all
the the files in a directory for them.
