This topic provides instructions to modify a configured Hadoop environment.

To edit a Hadoop environment

  1. From the PATROL Console work area, right-click the Hadoop Environment application instances you want to edit. Navigate to KM Commands > Edit Hadoop Environment menu command. This menu command opens the Register Hadoop environment dialog box with the environment name.
  2. Enter the information, as follows: 
    1. Hadoop connection details, 
      1. Hadoop Vendor -  Select the monitored Hadoop vendor. The supported vendors are:
        • Apache Hadoop
        • Big Insite
        • Cloudera
        • Horton
        • Map R
      2. Hadoop Host - Enter a unique, user-defined host name or an IP address.
      3. Hadoop Port - Enter the Hadoop port number. This port number depends on the component you want to monitor. If you want to monitor ResourceManager, enter the ResourceManager port number. Default port number is NameNode port, 50070.
      4. Hadoop User - Enter the user name to connect to the Hadoop server.
      5. Hadoop Password - Enter the password required to connect to the Hadoop server.
      6. Secure (HTTPS) - Select this checkbox if you want to use HTTPs protocol for connection. By default, HTTP protocol is used for connection.
      7. Trust Store - If you select to use HTTPs protocol for connection, you must provide the location to the Java Keystore File (JKS) for a successful connection to the URL in a secure mode.
      8. Trust Password - Enter the password to the JKS file.
    2. Enter the Java collector settings,
      1. JAVA_HOME - Enter the directory path where you have installed Java version 1.7 or later. 
      2. Executing user - Enter the local administrator user name. The executing username and password must have permissions to run Java.
      3. Executing password - Enter the local administrator password.
    3. Enter the Collection details,
      1. Availability -  Enables monitoring of the Hadoop monitored groups availability (if instance is running or is down) of one of the following instances existing in the environment:
          1. NameNode
          2. SecondaryNameNode
          3. ResourceManager
          4. DataNode
          5. NodeManager
          6. JobHistory
          7. JobTracker
          8. TaskTracker
      2. Full - Enables the monitoring of all Hadoop monitored groups, like UGIMetrics, StartUpProgress, and other groups.
      3. Custom -  Manually select the Hadoop monitored groups to monitor. A screenshot  of the custom monitoring option is given below:
