I have a doubt about how this works. The API documentation says that the class LocalDirAllocator is: "An implementation of a round-robin scheme for disk allocation for creating files" I am wondering, the disk allocation is done in the constructor? Let's say I have a cluster of just 1 node and 4 disks and I do inside a reducer: LocalDirAllocator localDirAlloc = new LocalDirAllocator("mapred.local.dir"); Path pathA = localDirAlloc.getLocalPathForWrite("a") ; Path pathB = localDirAlloc.getLocalPathForWrite("b") ;
The local paths pathA and pathB will for sure be in the same local disk as it was allocated by new LocalDirAllocator("mapred.local.dir") or is getLocalPathForWrite who gets the disk and so the two paths might not be in the same disk (as I have 4 disks)?
