      Description

      Hi, I am trying to start the namenode but it keeps showing: Failed to start namenode. java.net.BindException: Address already in use;. netstat -a | grep 9000 returns
      tcp 0 0 :9000 *: LISTEN
      tcp6 0 0 [::]:9000 [::]:* LISTEN

      Is this normal or do I need to kill one of the processes?

      The hdfs-site.xml is given below: <configuration> <property> <name>dfs.replication</name> <value>1</value> </property> <property> <name>dfs.namenode.name.dir</name> <value>file:///usr/local/hdfs/namenode</value> </property> <property> <name>dfs.datanode.data.dir</name> <value>file:///usr/local/hdfs/datanode</value> </property> </configuration>

      namenode logs are given below:
