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.
> Sort Use TableOrderPartitioner cannot find the path of _partition.lst int the
> container cwd.
