Install Hortonworks Data Platform

Install Hortonworks Data Platform on your cluster hardware and later configure high availability.

1. Make sure that you specify the virtual machine as your NameNode.
2. Download the Apache Ambari repository.

   	Note
   	Do not start the Ambari server until you have configured the relevant templates as outlined in the following steps.

3. Edit the <master-install-machine-for-Hive-Metastore>/etc/hive/conf.server/hive-site.xml configuration file to add the following properties:
   • Provide the URI for the client to contact Metastore server. The following property can have a comma separated list when your cluster has multiple Hive Metastore servers.

     <property>
      <name>hive.metastore.uris</name>
      <value>thrift://$Hive_Metastore_Server_Host_Machine_FQDN</value>
      <description>URI for client to contact Metastore server</description>
     </property>

   • Configure Hive cluster delegation token storage class.

     <property>
      <name>hive.cluster.delegation.token.store.class</name>
      <value>org.apache.hadoop.hive.thrift.ZooKeeperTokenStore</value>
     </property>

   • Complete Hortonworks Data Platform installation.
