tS3Configuration properties for Apache Spark Streaming – Docs for ESB 6.x

tS3Configuration properties for Apache Spark Streaming

These properties are used to configure tS3Configuration running in the Spark Streaming Job framework.

The Spark Streaming
tS3Configuration component belongs to the Storage family.

The component in this framework is available only if you have subscribed to Talend Real-time Big Data Platform or Talend Data
Fabric.

Basic settings

Access Key

Enter the access key ID that uniquely identifies an AWS Account. For
further information about how to get your Access Key and Secret Key, see Getting Your AWS Access
Keys
.

Access Secret

Enter the secret access key, constituting the security credentials in
combination with the access Key.

To enter the secret key, click the […] button next to
the secret key field, and then in the pop-up dialog box enter the password between double
quotes and click OK to save the settings.

Bucket name

Enter the bucket name and its folder you need to use. You need to separate
the bucket name and the folder name using a slash (/).

Use s3a filesystem

Select this check box to use the S3A filesystem instead of S3N, the
filesystem used by default by tS3Configuration.

This feature is available when you are using one of the following
distributions with Spark:

  • Amazon EMR

    • V4.5

    • V.4.6

  • MapR

    • V5.0

    • V5.1

    • V5.2

  • Hortonworks Data Platform

    • V2.3

    • V2.4

Set region

Select this check box and select the region to connect to.

This feature is available when you are using one of the following
distributions with Spark:

  • Amazon EMR

    • V4.5

    • V.4.6

  • MapR

    • V5.0

    • V5.1

    • V5.2

  • Hortonworks Data Platform

    • V2.3

    • V2.4

Set endpoint

Select this check box and in the Endpoint field that is displayed, enter the Amazon region endpoint
you need to use. For a list of the available endpoints, see Regions and Endpoints.

If you leave this check box clear, the endpoint will be the default one
defined by your Hadoop distribution, while this check box is not available when you
have selected the Set region check box and in
this situation the value selected from the Set
region
list is used.

This feature is available when you are using one of the following
distributions with Spark:

  • Amazon EMR

    • V4.5

    • V.4.6

  • MapR

    • V5.0

    • V5.1

    • V5.2

  • Hortonworks Data Platform

    • V2.3

    • V2.4

Usage

Usage rule

This component is used with no need to be connected to other components.

You need to drop tS3Configuration
along with the file system 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 Streaming component Palette it belongs to, appears
only when you are creating a Spark Streaming 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.

Spark Connection

You need to use the Spark Configuration tab in
the Run view to 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: when using Google
    Dataproc, specify a bucket in the Google Storage staging
    bucket
    field in the Spark
    configuration
    tab; when using other distributions, use a
    tHDFSConfiguration
    component to specify the directory.

  • Standalone mode: you need to choose
    the configuration component depending on the file system you are using, such
    as tHDFSConfiguration
    or tS3Configuration.

This connection is effective on a per-Job basis.

Limitation

Due to license incompatibility, one or more JARs required to use this component are not
provided. You can install the missing JARs for this particular component by clicking the
Install button on the Component tab view. You can also find out and add all missing JARs easily on the
Modules tab in the
Integration
perspective of your
studio. You can find more details about how to install external modules in Talend Help Center (https://help.talend.com).
