> HDFS-2832 enables support for heterogeneous storages in HDFS, which allows DN
> as a collection of storages with different types. However, I can't find
> document on how to label different storage types from the following two
> documents. I found the information from the design spec. It will be good we
> document this for admins and users to use the related Archival storage and
> storage policy features.
> http://hadoop.apache.org/docs/r2.6.0/hadoop-project-dist/hadoop-hdfs/ArchivalStorage.html
> http://hadoop.apache.org/docs/r2.6.0/hadoop-project-dist/hadoop-hdfs/hdfs-default.xml
> This JIRA is opened to add document for the new storage type labels.
> 1. Add an example under ArchivalStorage.html#Configuration section:
> {code}
> <property>
> <name>dfs.data.dir</name>
> <value>[DISK]file:///hddata/dn/disk0,
> [SSD]file:///hddata/dn/ssd0,[ARCHIVE]file:///hddata/dn/archive0</value>
> </property>
> {code}
> 2. Add a short description of [DISK/SSD/ARCHIVE/RAM_DISK] options in
> hdfs-default.xml#dfs.data.dir and document DISK as storage type if no storage
> type is labeled in the data node storage location configuration.
