>
> Now Hadoop support different storage type for DISK, SSD, ARCHIVE and RAM_DISK, but they
share one configuration dfs.datanode.du.reserved.
> The DISK size may be several TB and the RAM_DISK size may be only several tens of GB.
> The problem is that when I configure DISK and RAM_DISK (tmpfs) in the same DN, and I
set  dfs.datanode.du.reserved values 10GB, this will waste a lot of RAM_DISK size. 
> Since the usage of RAM_DISK can be 100%, so I don't want dfs.datanode.du.reserved configured
for DISK impacts the usage of tmpfs.
> So can we make a new configuration for RAM_DISK or just skip this configuration for RAM_DISK?
