      Description

      PROBLEM: When using Ambari UI to add second NameNode storage directory, Ambari fails to produce correct configuration in hdfs-site.xml

      STEPS TO REPRODUCE:

      1. Stop HDFS and MapReduce on the cluster
      2. Go to Ambari UI and navigate to Services Tab and select HDFS
      3. Click on Configs Tab under HDFS
      4. Add second NameNode storage directory using format below:

      /hadoop/hdfs/namenode
      /hadoop1/hdfs/namenode

      5. Save configuration
      6. Start HDFS

      ACTUAL BEHAVIOR: Ambari fails to start HDFS.

      EXPECTED BEHAVIOR: To be able to make configuration change and to start HDFS.

      Configuration in UI was done similar as during installation process - not using comma separated values. However, this is not transfered correctly to hdfs-site.xml. See below the configuration produced by Ambari:

      </property>
      <property>
      <name>dfs.name.dir</name>
      <value>/hadoop/hdfs/namenode
      /hadoop1/hdfs/namenode</value>
      </property>

      Please note that the values are not comma separated as needed for correct configuration to work.

      I was able to make configuration work by making following config in UI:

      /hadoop/hdfs/namenode,/hadoop1/hdfs/namenode

      This produced correct config in hdfs-site.xml.

      Please note that during installation input values entering one location per line and produces correct configuration. Also, there is no guidance in UI to specify how to configure this correctly.
