# tHBaseConfiguration properties for Apache Spark Batch These properties are used to configure tHBaseConfiguration running in the Spark Batch Job framework. The Spark Batch tHBaseConfiguration component belongs to the Storage and the Databases families. The component in this framework is available in all subscription-based Talend products with Big Data and Talend Data Fabric. ## Basic settings | Properties | Description | | --- | --- | | Property type | Either Built-In or Repository.


Built-In: No property data stored centrally.


Repository: Select the repository file where the
properties are stored. | | HBase version | Select the HBase version of the distribution you are using. | | Zookeeper quorum | Type in the name or the URL of the ZooKeeper service you use to coordinate the
transaction between your Talend Studio and
your database. Note that when you configure the ZooKeeper, you might need to explicitly
set the *zookeeper.znode.parent* property to define the path to the
root Znode that contains all the Znodes created and used by your database; then select
the Set Zookeeper znode parent check box to define
this property. | | Zookeeper client port | Type in the number of the client listening port of the ZooKeeper service you
are using. | | Use kerberos
authentication | If the database to be used is running with Kerberos security, select this
checkbox, then, enter the principal names in the HBase Master
principal and HBase Region Server principal
fields. You should be able to find the information in the *hbase-site.xml* file of the cluster to be used.

If you need to use a Kerberos keytab file to log in, select Use a keytab to authenticate. A keytab file contains
pairs of Kerberos principals and encrypted keys. You need to enter the principal to
be used in the Principal field and the access
path to the keytab file itself in the Keytab
field. This keytab file must be stored in the machine in which your Job actually
runs, for example, on a Talend JobServer.

Note that the user that executes a keytab-enabled Job is not necessarily
the one a principal designates but must have the right to read the keytab file being
used. For example, the username you are using to execute a Job is *user1* and the principal to be used is *guest*; in this
situation, ensure that *user1* has the right to read the keytab
file to be used. | | HBase parameters | If you need to use custom configuration for your database, complete this
table with the property or properties to be customized. Then at runtime, the customized
property or properties will override the corresponding ones used by Talend Studio. | ## Usage | Usage guidance | Description | | --- | --- | | **Usage rule** | This component is used with no need to be connected to other
components.

You must drop tHBaseConfiguration along with the
HBase-related subJob to be run in the same Job so that the configuration is used by the
whole Job at runtime.

This component, along with the Spark Batch component Palette it belongs to,
appears only when you are creating a Spark Batch Job.

Note that in this documentation, unless otherwise explicitly stated, a
scenario presents only Standard Jobs, that is to
say traditional
Talend
data integration Jobs. | | Prerequisites | Before starting, ensure that you have met the Loopback IP prerequisites expected by your
database.

For further information about how to install a Hadoop distribution, see the manuals
corresponding to the Hadoop distribution you are using. | | Spark Connection | In the Spark
Configuration tab in the Run
view, define the connection to a given Spark cluster for the whole Job. In
addition, since the Job expects its dependent jar files for execution, you must
specify the directory in the file system to which these jar files are
transferred so that Spark can access these files:



This connection is effective on a per-Job basis. |
