Possible to reserve 0 from various testing I have done yet that could cause the obvious side
effect of achieving zero disk space:) Have only tested in development environment, however.
Yet there are various tuning white papers and other benchmarks where the very same has been
tested. 



Thanks.

the parameter: dfs.datanode.du.reserved is used to reserve disk space PER datanode. Is it
possible to reserve a different amount of disk space per DISK?


thanks
