Andrew Hitchcock updated HADOOP-5635:
-------------------------------------
Attachment: fix-distributed-cache.patch
This patch removes the check for HDFS and lets any file system through. The
onus is on the user to ensure that the file system is globally available on all
nodes.
> distributed cache doesn't work with other distributed file systems
> ------------------------------------------------------------------

> Key: HADOOP-5635
> URL: https://issues.apache.org/jira/browse/HADOOP-5635
> Project: Hadoop Core
> Issue Type: Bug
> Components: filecache
> Reporter: Andrew Hitchcock
> Priority: Minor
> Attachments: fix-distributed-cache.patch
>
>
> Currently the DistributedCache does a check to see if the file to be included
> is an HDFS URI. If the URI isn't in HDFS, it returns the default filesystem.
> This prevents using other distributed file systems -- such as s3, s3n, or kfs
> -- with distributed cache. When a user tries to use one of those
> filesystems, it reports an error that it can't find the path in HDFS.
