[jira] [Commented] (MAPREDUCE-5782) Sort Use TableOrderPartitioner cannot find the path of _partition.lst int the container cwd.

["Bing Jiang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5782?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13923635#comment-13923635 ] 

Bing Jiang commented on MAPREDUCE-5782:
---------------------------------------

Checking the code, 

========org.apache.hadoop.examples.Sort========
      URI partitionUri = new URI(partitionFile.toString() +
                                 "#" + "_sortPartitioning");
      DistributedCache.addCacheFile(partitionUri, conf);

which rename default name '_partition.lst' into '_sortPartitioning' when container finishes localization.
So the problem can be tackled by add  -Dmapreduce.totalorderpartitioner.path=_sortPartitioning 
or remove the setting of symlink here.
