Zheng Shao commented on MAPREDUCE-1302: --------------------------------------- MAPREDUCE-1141 is fixed by this patch. > TrackerDistributedCacheManager can delete file asynchronously > ------------------------------------------------------------- > > Key: MAPREDUCE-1302 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1302 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: tasktracker > Affects Versions: 0.20.2, 0.21.0, 0.22.0 > Reporter: Zheng Shao > Assignee: Zheng Shao > Attachments: MAPREDUCE-1302.0.patch, MAPREDUCE-1302.1.patch, > MAPREDUCE-1302.2.patch > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
