Adding the HBase App When You Create a New Hadoop Pseudoclient

You can add the HBase App when you create a new Hadoop pseudoclient from the CommCell Console.

Procedure

  1. From the CommCell Browser, right-click Client Computers, point to New Client > File System, and then click Hadoop.

    The Create Hadoop Client dialog box appears.

  2. To connect to the Hadoop cluster, enter the HDFS URI host and user details:
    1. In the Client Name box, type a name for the pseudoclient.
    2. In the Instance Name box, type a name for the instance.
    3. In the HDFS URI box, type the fully qualified domain name (FQDN) of the Hadoop NameNode.

      Important: If you select the default HDFS URI, the URI details are fetched from the core-site.xml file. The core-site.xml file is located under the hadoop_installation_directory/conf/ directory.

    4. Optional: If a non-root user account is used to manage the Hadoop cluster, in the HDFS User box, type the Hadoop username.
    5. In the Hadoop Native Library Path box, enter the path to the Hadoop native library (libhdfs.so).

      For example, enter /usr/hadoop-2.6.1/lib/native.

    6. In the JVM Library Path box, enter the path to the JVM library (libjvm.so).

      For example, enter /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.45.x86_64/jre/lib/amd64/server.

  3. On the Hadoop tab, specify the data access nodes that you want to add to the instance:
    1. From the Master Node list, select the data access node to use as a master node for the instance.
    2. Under Data Access Nodes, select the data access nodes, and then click Add.
    3. In the Number of Data Readers box, enter the number of data streams that you want to use for the backup operation.

      Tip: For optimal sharing of the backup load, the number of data readers must be greater than the number of data access nodes.

  4. On the Storage Device tab, from the Storage Policy list, select a storage policy.
  5. On the Hadoop Apps tab, click Add.
  6. Click HBase.

    The Configure Hadoop Apps dialog box appears.

  7. Configure the HBase App properties:
    1. From the HBase Node list, select the HBase node.
    2. If a non-root user account is used to manage the Hadoop cluster, in the HBase User box, type the HBase user name.
    3. In the HBase Configuration File box, type the path to the HBase configuration file.

      For example, type /etc/hbase/conf.

    4. In the Java Path box, enter the path to the JVM library (libjvm.so).

      For example, enter /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.45.x86_64/je/lib/amd64/server.

    5. In the Backup Root box, type the HBase backup root path.

      For example, type /hbase_bkuproot.

    6. In the Authentication Settings area, click Configure.

      The Authentication Settings dialog box appears.

    7. Enter the following information:
      1. In the User Name box, type the HBase username.
      2. In the Password box, type the password for the HBase username.
      3. In the Confirm Password box, re-type the password for the HBase username.
  8. Click OK.
