Subject [jira] [Created] (HDFS-11049) The description of dfs.block.replicator.classname is not clearly
Date Tue, 25 Oct 2016 08:39:58 GMT
Yiqun Lin created HDFS-11049:

             Summary: The description of dfs.block.replicator.classname is not clearly
                 Key: HDFS-11049
                 URL: https://issues.apache.org/jira/browse/HDFS-11049
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: documentation
    Affects Versions: 3.0.0-alpha1
            Reporter: Yiqun Lin
            Assignee: Yiqun Lin
            Priority: Minor

Now the description of the property {{dfs.block.replicator.classname}} seems not clearly.
The current description:
  <name>dfs.block.replicator.classname</name>  <value>org.apache.hadoop.hdfs.server.blockmanagement.BlockPlacementPolicyDefault</value>
    Class representing block placement policy for non-striped files.
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.

This JIRA foucus on making a improvement for this in file {{hdfs-default.xml}}
