title: HDFS write resulting in " CreateSymbolicLink error (1314): A required privilege is not held by the client."
body: <p>Tried to execute sample map reduce program from <a href="http://hadoop.apache.org/docs/current/hadoop-mapreduce-client/hadoop-mapreduce-client-core/MapReduceTutorial.html#Example:_WordCount_v1.0" rel="nofollow noreferrer">Apache Hadoop</a>. Got exception below when map reduce job was running. Tried <code>hdfs dfs -chmod 777 /</code> but that didn't fix the issue.</p>
