Shinichi Yamashita commented on YARN-925:
-----------------------------------------

Thank you for the check of the patch.
As you say, the current patch is not good for a histroy of huge application.
I thought about a plan to add filter information to a history file name and a plan to add
find command to HDFS.
However, I thought that your idea was simple and better than mine.

I think about a better method.

> We need to allow filter parameters for getApplications, pushing filtering to the implementations
of the interface. The implementations should know the best about optimizing filtering.
