Vinod K V commented on MAPREDUCE-1302: -------------------------------------- Zheng, sorry for the delay, got caught up with other things. MAPREDUCE-1186 got committed which invalidated your latest patch. It changed the constructor of MRAsyncDiskService and Tasktracker.initialize(). Can you please generate a new one? I myself manually merged the changes for review of code. Rest of the changes look good. I'll do a +1 once you upload the updated patch. Thanks for being patient! > 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, MAPREDUCE-1302.3.patch, MAPREDUCE-1302.4.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.
