      Description

      As part of the upgrade domain feature, we need to provide a mechanism to specify upgrade domain for each datanode. One way to accomplish that is to allow admins specify an upgrade domain script that takes DN ip or hostname as input and return the upgrade domain. Then namenode will use it at run time to set DatanodeInfo's upgrade domain string. The configuration can be something like:

      <property>
      <name>dfs.namenode.upgrade.domain.script.file.name</name>
      <value>/etc/hadoop/conf/upgrade-domain.sh</value>
      </property>
      

      just like topology script,
