I am using CDH 5.6.0 and want to set tired storage by CM. However it seems this version of CM does not support prefix like [ARCHIVE]. I found a similar thread here: https://community.cloudera.com/t5/Storage-Random-Access-HDFS/How-to-define-HDFS-storage-tiers-and-st... I follow the solution to set data dir in the "DataNode Advanced Configuration Snippet (Safety Valve) for hdfs-site.xml" . And I want to set all my disks as archive storage, which needs the data.dir setting to be empty, which is not allowed by CM. Any idea?

I noticed that setting storage type is supported since CDH 5.7 from here. Does it mean I should upgrade CDH and CM to a higher version or just upgrading CM will work?
