Bryan Pendleton commented on HADOOP-27: --------------------------------------- I still think this issue is important. The point of MapReduce is to squeeze as much performance out of what you've got as possible. I regularly have machines with hundreds of gigs of space fail because one of their 4 drives is full. And, yes, the cascading failure problem is the real kicker. It sounds like your patch attacks both of those things - as soon as I have a chance, I'll test it against my current cluster and see how it performs. > MapRed tries to allocate tasks to nodes that have no available disk space > ------------------------------------------------------------------------- > > Key: HADOOP-27 > URL: http://issues.apache.org/jira/browse/HADOOP-27 > Project: Hadoop > Type: Bug > Components: mapred > Reporter: Mike Cafarella > Attachments: minspace_mapredtask.patch > > What it says above.
