4. Click Upload.

You can specify multiple addresses and address ranges by separating them by commas, semicolons, tabs, or blank spaces, or by placing them on separate lines. Use this technique to make more specific searches instead of searching overly wide ranges. The scan results will include all addresses scanned, but only scans that reach hosts running SSH will be selected for inclusion in your cluster by default. If you don't know the IP addresses of all of the hosts, you can enter an address range that spans over unused addresses and then deselect the hosts that do not exist (and are not discovered) later in this procedure. However, keep in mind that wider ranges will require more time to scan.

• Use Parcels:
  1. Choose the parcels to install. The choices you see depend on the repositories you have chosen – a repository may contain multiple parcels. Only the parcels for the latest supported service versions are configured by default.
     You can add additional parcels for previous versions by specifying custom repositories. For example, you can find the locations of the previous CDH 4 parcels at http://archive.cloudera.com/cdh4/parcels/. Or, if you are installing CDH 4.3 and want to use Sentry for Hive Authorization, you can add the Sentry parcel using this mechanism. To add a custom parcel repository:

     1. Enter the URL of the repository into More Options field, and click the + Add button. The URL you specify is added to the list of repositories listed in the Configuring Server Parcel Settings page and a parcel is added to the list of parcels on the Select Repository page. If you have multiple repositories configured, you will see all the unique parcels contained in all your repositories.
• Use Packages:
  1. Select the major release of CDH to install.
  2. Select the specific release of CDH to install.
  3. Select the specific releases of Impala and Solr to install, assuming you have selected an appropriate CDH version. You can choose either the latest version or use a custom repository. Choose None if you do not want to install that service.

1. Select root or enter the user name for an account that has password-less sudo permission.
2. Select an authentication method:
   • If you choose to use password authentication, enter and confirm the password.
   • If you choose to use public-key authentication provide a passphrase and path to the required key files.
3. You can choose to specify an alternate SSH port. The default value is 22.
4. You can specify the maximum number of host installations to run at once. The default value is 10.

• Parcels - installs the Oracle JDK and the Cloudera Manager Agent packages and starts the Agent. Click Continue. During the parcel installation, progress is indicated for the two phases of the parcel installation process (Download and Distribution) in a separate progress bars. If you are installing multiple parcels you will see progress bars for each parcel. When the Continue button appears at the bottom of the screen, the installation process is completed.
• Packages - configures package repositories, installs the Oracle JDK, CDH and managed service and the Cloudera Manager Agent packages, and starts the Agent. When the Continue button appears at the bottom of the screen, the installation process is completed. If the installation has completed successfully on some hosts but failed on others, you can click Continue if you want to skip installation on the failed hosts and continue to the next screen to start configuring services on the successful hosts.

• Click the radio button next to the combination of services to install:

  CDH 4	CDH 5
  Core Hadoop - HDFS, MapReduce, ZooKeeper, Oozie, Hive, and Hue Core with HBase Core with Impala All Services - HDFS, MapReduce, ZooKeeper, HBase, Impala, Oozie, Hive, Hue, and Sqoop Custom Services - Any combination of services.	Core Hadoop - HDFS, YARN (includes MapReduce 2), ZooKeeper, Oozie, Hive, Hue, and Sqoop Core with HBase Core with Impala Core with Search Core with Spark All Services - HDFS, YARN (includes MapReduce 2), ZooKeeper, Oozie, Hive, Hue, Sqoop, HBase, Impala, Solr, Spark, and Key-Value Store Indexer Custom Services - Any combination of services.

  As you select the services, keep the following in mind:
  • Some services depend on other services; for example, HBase requires HDFS and ZooKeeper. Cloudera Manager tracks dependencies and installs the correct combination of services.
  • In a CDH 4 cluster, the MapReduce service is the default MapReduce computation framework. Choose Custom Services to install YARN or use the Add Service functionality to add YARN after installation completes.
      Important: You can create a YARN service in a CDH 4 cluster, but it is not considered production ready.
  • In a CDH 5 cluster, the YARN service is the default MapReduce computation framework. Choose Custom Services to install MapReduce or use the Add Service functionality to add MapReduce after installation completes.
      Important: In CDH 5 the MapReduce service has been deprecated. However, the MapReduce service is fully supported for backward compatibility through the CDH 5 life cycle.
  • The Flume service can be added only after your cluster has been set up.
• If you have chosen Data Hub Edition Trial or Cloudera Enterprise, optionally check the Include Cloudera Navigator checkbox to enable Cloudera Navigator. See the Cloudera Navigator Documentation.

Click a field below a role to display a dialog containing a pageable list of hosts. If you click a field containing multiple hosts, you can also select All Hosts to assign the role to all hosts or Custom to display the pageable hosts dialog.

Click the View By Host button for an overview of the role assignment by host ranges.

1. Choose the database type:
   • Leave the default setting of Use Embedded Database to have Cloudera Manager create and configure all required databases. Make a note of the auto-generated passwords.
   • Select Use Custom Databases to specify external databases. Enter the database host, database type, database name, username, and password for the databases that you created when you set up databases for Cloudera Manager.
     1. Provide information for the Activity Monitor (only needed when using MapReduce), Reports Manager, and Hive Metastore, and Cloudera Navigator databases. The value you enter as the database hostname must match the value you entered for the hostname (if any) when you created the database.
2. Click Test Connection to confirm that Cloudera Manager can communicate with the databases using the information you have supplied. If the test succeeds in all cases, click Continue; otherwise check and correct the information you have provided for the databases and then try the test again. (For Hive, if you are using the embedded database, you will see a message saying the database will be created at a later point in the installation process.) The Review Changes page displays.
