tBigQueryConfiguration

Provides the connection configuration to Google BigQuery and Google Cloud Storage
for a Spark Job.

tBigQueryConfiguration properties for Apache Spark Batch

These properties are used to configure tBigQueryConfiguration running in the Spark Batch Job framework.

The Spark Batch
tBigQueryConfiguration 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

When you use this component with Google Dataproc:

BigQuery temp GCS path	Enter the directory on Google Storage to temporarily store the data to be used with Google BigQuery. If not existing yet, this directory is created on the fly but the bucket that contains this directory must already exist. The syntax of the directory should be gs://my_bucket/my_directory. When you use Google BigQuery with Dataproc, in Google Cloud Platform, select the same region for your BigQuery dataset as for the Dataproc cluster to be run.
Location	Select one of the Google multi-regional locations in which you want to read or write data. The resource dataset and the target dataset must be in the same location. In Spark Jobs, only the US and the EU locations are supported. For further information about Google locations and how to properly use the locations, see Dataset Locations from Google documentation.

BigQuery temp GCS path

Enter the directory on Google Storage to temporarily
store the data to be used with Google BigQuery. If not existing yet,
this directory is created on the fly but the bucket that contains this
directory must already exist. The syntax of the directory should be
gs://my_bucket/my_directory.

When you use Google BigQuery with Dataproc, in
Google Cloud Platform, select the same region for your BigQuery dataset
as for the Dataproc cluster to be run.

Location

Select one of the Google multi-regional locations in which you want to
read or write data. The resource dataset and the target dataset must be in
the same location.

In Spark Jobs, only the US and the EU locations are supported.

For further information about Google locations and how
to properly use the locations, see Dataset Locations from Google
documentation.

When you use this component with the other distributions

Project identifier	Enter the ID of your Google Cloud Platform project. If you are not certain about your project ID, check it in the Manage Resources page of your Google Cloud Platform services.
Path to Google Credentials file	Enter the path to the credentials file associated to the user account to be used. This file must be stored in the machine in which your Talend Job is actually launched and executed. If you use Talend Jobserver to run your Job, store the credentials file not only in the machine of the Jobserver, in which the Job is launched, but also in the worker machines of the Spark cluster, in which the Job is executed; if you do not use the Jobserver, store the credentials file in your local machine from which you launch the Job and in the worker machines of the Spark cluster.
Use P12 credentials file format	When the Google credentials file to be used is in P12 format, select this check box and then in the Service account Id field that is displayed, enter the ID of the service account for which this P12 credentials file has been created.
BigQuery temp GCS path	Enter the directory on Google Storage to temporarily store the data to be used with Google BigQuery. If not existing yet, this directory is created on the fly but the bucket that contains this directory must already exist. The syntax of the directory should be gs://my_bucket/my_directory. When you use Google BigQuery with Dataproc, in Google Cloud Platform, select the same region for your BigQuery dataset as for the Dataproc cluster to be run.
Location	Select one of the Google multi-regional locations in which you want to read or write data. The resource dataset and the target dataset must be in the same location. In Spark Jobs, only the US and the EU locations are supported. For further information about Google locations and how to properly use the locations, see Dataset Locations from Google documentation.

Usage

Usage rule	This component is used standalone in a subJob to provide connection configuration to Google BigQuery and Google Storage for the whole Job.
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: Yarn mode (Yarn client or Yarn cluster): When using Google Dataproc, specify a bucket in the Google Storage staging bucket field in the Spark configuration tab. When using HDInsight, specify the blob to be used for Job deployment in the Windows Azure Storage configuration area in the Spark configuration tab. When using Altus, specify the S3 bucket or the Azure Data Lake Storage for Job deployment in the Spark configuration tab. When using Qubole, add a tS3Configuration to your Job to write your actual business data in the S3 system with Qubole. Without tS3Configuration, this business data is written in the Qubole HDFS system and destroyed once you shut down your cluster. When using on-premise distributions, use the configuration component corresponding to the file system your cluster is using. Typically, this system is HDFS and so use tHDFSConfiguration. Standalone mode: use the configuration component corresponding to the file system your cluster is using, such as tHDFSConfiguration or tS3Configuration. If you are using Databricks without any configuration component present in your Job, your business data is written directly in DBFS (Databricks Filesystem). This connection is effective on a per-Job basis.

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:

Yarn mode (Yarn client or Yarn cluster):
- When using Google Dataproc, specify a bucket in the
  Google Storage staging bucket
  field in the Spark configuration
  tab.
- When using HDInsight, specify the blob to be used for Job
  deployment in the Windows Azure Storage
  configuration area in the Spark
  configuration tab.
- When using Altus, specify the S3 bucket or the Azure
  Data Lake Storage for Job deployment in the Spark
  configuration tab.
- When using Qubole, add a
  tS3Configuration to your Job to write
  your actual business data in the S3 system with Qubole. Without
  tS3Configuration, this business data is
  written in the Qubole HDFS system and destroyed once you shut
  down your cluster.
- When using on-premise
  distributions, use the configuration component corresponding
  to the file system your cluster is using. Typically, this
  system is HDFS and so use tHDFSConfiguration.
Standalone mode: use the
configuration component corresponding to the file system your cluster is
using, such as tHDFSConfiguration or
tS3Configuration.

If you are using Databricks without any configuration component present
in your Job, your business data is written directly in DBFS (Databricks
Filesystem).

This connection is effective on a per-Job basis.
