      Description

      As part of the upgrade domain feature, we need to provide the actual upgrade domain block placement.

      Namenode provides a mechanism to specify custom block placement policy. We can use that to implement BlockPlacementPolicy with upgrade domain support.

      <property>
      <name>dfs.block.replicator.classname</name>
      <value>org.apache.hadoop.hdfs.server.blockmanagement.BlockPlacementPolicyWithUpgradeDomain</value>
      </property>
