    there is a need for creating empty dfs.exclude and dfs.include files in etc folder of hadoop install, else due to

    hdfs-site.xml configuration

    <property>
    <name>dfs.hosts</name>
    <value>D:/Apps/java/BI/hadoop/hw/hdp/hadoop-2.2.0.2.0.6.0-0009/etc/hadoop/dfs.include</value>
    </property>

    <property>
    <name>dfs.hosts.exclude</name>
    <value>D:/Apps/java/BI/hadoop/hw/hdp/hadoop-2.2.0.2.0.6.0-0009/etc/hadoop/dfs.exclude</value>
    </property>

    would result in file not found exception.

    True, few of the servers were not starting. Server log shows file not found error and it does not start there on.

    Hi Raja,
    Are you stating that if the file does not exist, namenode will not start? Or you are seeing errors in the namenode logs regarding the lack of these files?

    Regards,
    Robert
