Harsh J resolved MAPREDUCE-458. ------------------------------- Resolution: Not A Problem This discussion has gone stale. I wonder if we see major issues with current DistributedCache features today that does proper caching and works across jobs too. > Adding caching to Hadoop which is independent of the task trackers. > ------------------------------------------------------------------- > > Key: MAPREDUCE-458 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-458 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Reporter: Mahadev konar > Assignee: Owen O'Malley > Priority: Minor > > It would be nice to have a feature in Hadoop that could cache files locally > that is independent of TaskTrackers and JobTrackers. Hadoop-288 caching is > dependent on the tasktrackers. In an environment where you would dynamically > bring up and down the TaskTrackers for resource sharing, that is problematic. > It would be good to have this feature wherein you can install > tasktrackers/jobtrackers on these machines using this caching mechanism. The > caching feature could use something like Bittorent /http/rsync to copy the > main hadoop.jar. -- This message is automatically generated by JIRA.
