Subject [jira] [Commented] (HDFS-1564) Make dfs.datanode.du.reserved configurable per volume
Date Mon, 10 Sep 2012 09:48:08 GMT

Assaf Yardeni commented on HDFS-1564:
-------------------------------------

Hello,
In my use-case having the "dfs.datanode.du.pct" reintroduce will be great. We have different
disk sizes on our DNs.
I don't think it makes sense to have multiple entries (per disk), that doesn't scale in terms
of operations.

> In clusters with DNs which have heterogeneous data dir volumes, it would be nice if dfs.datanode.du.reserved
could be configured per-volume.
