>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: documentation
>    Affects Versions: 3.0.0-alpha1
>            Reporter: Yiqun Lin
>            Assignee: Yiqun Lin

> 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}}.
