    Specify if using High Availability for DFS.

    DFS name service

    Specify the logical name of the HDFS nameservice.

    DFS name node IDs

    Specify a comma-separated list of NameNode IDs. System uses this property to determine all NameNodes in the cluster. XML property name is dfs.ha.namenodes.dfs.nameservices.

    RPC address for namenode1

    Specify the fully-qualified RPC address for each listed NameNode. Defined as dfs.namenode.rpc-address.dfs.nameservices.name node ID 1. For DFS HA and Hadoop Extract only.

    RPC address for namenode2

    Specify the fully-qualified RPC address for each listed NameNode. Define as dfs.namenode.rpc-address.dfs.nameservices.name node ID 2.

    DFS host

    Specify the DFS hostname or the IP address.

    DFS port

    Specify the associated DFS port.

    Default DFS location

    Specify the location for the default source/target location.

    Temp DFS location

    Specify the location for creating temp directory.

    DFS security authentication

    Select the type of security being enabled.

    Hadoop RPC protection

    Hadoop cluster administrators control the quality of protection using the configuration parameter hadoop.rpc.protection.

    Hive principal

    Principal for authenticating hive services.

    User principal

    To authenticate via a key-tab you must have supporting key-tab file which is generated by Kerberos Admin and also requires the user principal associated with Key-tab (Configured while enabling Kerberos).

    User keytab

    To authenticate via a key-tab you must have supporting key-tab file which is generated by Kerberos Admin and also requires the user principal associated with Key-tab (Configured while enabling Kerberos).

    KDC host

    Specify KDC Host Name where as KDC (Kerberos Key Distribution Center) is a service than runs on a domain controller server role (Configured from Kerberos configuration-/etc/krb5.conf).

    Default realm

    A Kerberos realm is the domain over which a Kerberos authentication server has the authority to authenticate a user, host or service (Configured from Kerberos configuration-/etc/krb5.conf).

    Queue name

    Specify the queue name followed by a coma separated form in yarn.scheduler.capacity.root.queues. For Hadoop Extract only.

    YARN web UI port

    Yarn Providing web UI for yarn RM and by default 8088 in use. For Hadoop Extract only.

    Zookeeper quorum host

    Specify the value of hadoop.registry.zk.quorum from yarn-site.xml. Only when using Hiveserver2 HA.

    Yarn timeline webapp host

    Specify the ip address of yarn timeline service web application.
