if i specify multiple directories on separate disks in mapred.local.dir, will a task write to one of them, or to all of them?
and if one of those disks becomes full, will the task be smart enough to start writing to another directory that is on a disk that is not full? and really the same question asked slighly differently: when i see a task failing because there was no more space, could this be because one of those directories was on a full disk despite the fact that there was plenty of space in other directories in mapred.local.dir? thanks! koert
