TrackerDistributedCacheManager can delete file asynchronously
-------------------------------------------------------------
Key: MAPREDUCE-1302
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1302
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Zheng Shao
Assignee: Zheng Shao
With the help of AsyncDiskService from MAPREDUCE-1213, we should be able to
delete files from distributed cache asynchronously.
That will help make task initialization faster, because task initialization
calls the code that localizes files into the cache and may delete some other
files.
The deletion can slow down the task initialization speed.
