   @fengpod HBase 2.0+ already supports setting the Storage Policy at CF-level, see: [HBASE-14061](https://issues.apache.org/jira/browse/HBASE-14061) [HBASE-15172](https://issues.apache.org/jira/browse/HBASE-15172)
   
   Maybe we can set the storage strategy directly when creating the table. such as : 
   `create 'tablename',{NAME=>'f1',STORAGE_POLICY=>'ALL_SSD'},{NAME=>'f2',STORAGE_POLICY=>'ONE_SSD'}
   `
   
   @hit-lacus What do you think?
