Kousuke Saruta commented on HADOOP-7771:
----------------------------------------
In this jira, the name of the temp file has the suffix "._COPYING_" but I think
it can cause a bad effect when we run mapreduce.
When we run mapreduce, temp files should be ignored so we need to consider the
name of the temp file.
If you have no objections, I will create a jira about that.
