[jira] [Commented] (MRUNIT-161) some distributed cache apis not working - JobContext getCacheArchives()

["Brock Noland (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MRUNIT-161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13502791#comment-13502791 ] 

Brock Noland commented on MRUNIT-161:
-------------------------------------

There are bunch of methods relating to Dcache in JobContextImpl. They look easy enough to implement, we'd just need the configuration object to do so.

  public URI[] getCacheArchives() throws IOException {
    return DistributedCache.getCacheArchives(conf);
  }

> I'm using the new MRUnit method withCacheArchive available in 1.0.0.
> DistributedCache.getLocalCacheArchives(conf) returns a non-empty array, however
> org.apache.hadoop.mapreduce.JobContext.getCacheArchives()
> in the mapper returns null. It seems that the context mock doesn't have these methods implemented?
> I'm using hadoop2, where getLocalCacheArchives is listed as deprecated.
