    Description

      The Hadoop daemons (like datanode, namenode) should refuse to start up if the ownership/permissions on directories they use at runtime are misconfigured or they are not as expected. For example, the local directory where the filesystem image is stored should be owned by the user running the namenode process and should be only readable by that user. We can provide this feature in common and HDFS and MapReduce can use the same.
