Description

HDFS now support four kinds of heterogeneous storage types: ARCHIVE, DISK, SSD and RAM_DISK.
If we configure dfs.datanode.data.dir as [RAM_DISK]/anydir,it validates failed.
please see https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/ArchivalStorage.html#Configuration

HDP-2.3.4 has adopted this feature (HDFS-6581) listed in http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.4/bk_HDP_RelNotes/content/patch_hadoop.html
