# tHBaseOutput Standard properties These properties are used to configure tHBaseOutput running in the Standard Job framework. The Standard tHBaseOutput component belongs to the Big Data and the Databases NoSQL families. The component in this framework is available in all Talend products with Big Data and in 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. | | ![](https://help.qlik.com/talend/en-US/components/8.0/Resources/images/Save_Icon.png) | Click this icon to open a database connection wizard and store the
database connection parameters you set in the component Basic
settings view.

For more information about setting up and storing database connection
parameters, see [Centralizing database metadata](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/centralizing-database-metadata). | | Use an existing connection | Select this check box and in the Component
List drop-down list, select the desired connection component to
reuse the connection details you already defined. | | HBase version | Select the HBase version of the distribution you are using. | | Hadoop version | Select the Hadoop 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. | | Schema and Edit
schema | | | Specify namespace | Select this check box if you want to specify a namespace, and enter the name
of the namespace you want to create in the Namespace
parameter. | | Table name | Type in the name of the HBase table you need create. | | Action on table | Select the action you need to take for creating an HBase
table. | | Custom Row Key | Select this check box to use the customized row keys. Once
selected, the corresponding field appears. Then type in the user-defined row
key to index the rows of the HBase table being created.

For example, you can type in "France"+Numeric.sequence("s1",1,1) to produce the row key series:
France1, France2, France3 and so on. | | Families | Complete this table to map the columns of the table to be used with the schema columns you
have defined for the data flow to be processed.

The Column column of this table is
automatically filled once you have defined the schema; in the Family name column, enter the column families you want to create or use
to group the columns in the Column column. For more
information about a column family, see [Column families](http://hbase.apache.org/0.94/book/columnfamily.html) from Apache documentation. | | Custom timestamp column | Select a Long column from your schema to provide
timestamps for the HBase columns to be created or updated by
tHBaseOutput. | | Die on error | This check box is cleared by default, meaning to skip the row on
error and to complete the process for error-free rows. | ## Advanced settings | Properties | Description | | --- | --- | | Use batch mode | Select this check box to activate the batch mode for data processing. | | Batch size | Specify the number of records to be processed in each batch.

This field is available only when the Use batch mode
check box is selected. | | Properties | 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.

For example, you need to define the value of the *dfs.replication* property as *1* for the
database configuration. Then you need to add one row to this table using the plus button and
type in the name and the value of this property in this row.

Information noteNote:

This table is not available when you are using an existing
connection by selecting the Using an
existing connection check box in the Basic settings view. | | tStatCatcher Statistics | Select this check box to collect log data at the component
level. | | Family parameters | Type in the names and, when needs be, the custom performance options of the
column families to be created. These options are all attributes defined by the
HBase data model. For more information about a column family, see [Column families](http://hbase.apache.org/0.94/book/columnfamily.html) from Apache documentation.

Information noteNote: The parameter Compression type allows you to select the
format for output data compression. | ## Global Variables | Variables | Description | | --- | --- | | Global Variables | NB\_LINE: the number
of rows read by an input component or transferred to an output component. This is an
After variable and it returns an integer.


ERROR\_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This
variable functions only if the Die on error checkbox is
cleared, if the component has this checkbox.

A Flow variable functions during the execution of a component
while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from
it.

For more information about variables, see [Using contexts and variables](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/contexts-and-variables). | ## Usage | Usage guidance | Description | | --- | --- | | **Usage rule** | This component is normally an end component of a Job and always
needs an input link. | | Prerequisites | Before starting, ensure that you have met the Loopback IP prerequisites expected by your
database.

corresponding to the Hadoop distribution you are using. |
