Akira Ajisaka updated HDFS-11785:
---------------------------------
Hadoop Flags: Reviewed
Release Note: Reserved space can be configured independently for different
storage types for clusters with heterogeneous storage. The
'dfs.datanode.du.reserved' property name can be suffixed with a storage types
(i.e. one of ssd, disk, archival or ram_disk). e.g. reserved space for RAM_DISK
storage can be configured using the property
'dfs.datanode.du.reserved.ram_disk'. If specific storage type reservation is
not configured then the value specified by 'dfs.datanode.du.reserved' will be
used for all volumes.
LGTM, +1. The patch has one trailing whitespace, so {{--whitespace-fix}} option
is needed when applying the patch.
> Backport HDFS-9902 to branch-2.7: Support different values of
> dfs.datanode.du.reserved per storage type
