> Now the description of the property {{dfs.block.replicator.classname}} seems 
> not clearly. The current description:
> {code}
> <property>
>   <name>dfs.block.replicator.classname</name>  
> <value>org.apache.hadoop.hdfs.server.blockmanagement.BlockPlacementPolicyDefault</value>
>   <description>
>     Class representing block placement policy for non-striped files.
>   </description>
> </property>
> {code}
> It seems too simple and the users will not get the other available block 
> placement policies and its usage. For example in HDFS-7541, it introduced     
> a new policy {{BlockPlacementPolicyWithUpgradeDomain}}. This policy can be 
> good used in rolling upgrade opeations.
> In addition, I don't find other documentations that concretely introducing 
> the existing placement policies. This JIRA foucus on making a improvement for 
> this in file {{hdfs-default.xml}}.
