> 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.
