Configure the processor for your data target

This example use case shows you two options for ingesting data to Google Cloud Storage (GCS). Learn how you can configure these data NiFi processors for your GCS ingest flow.

  1. Launch the Configure Processor window by right clicking the processor you added for writing data to GCS (PutHDFSor PutGCSObject) and selecting Configure.
    This gives you a configuration dialog with the following tabs: Settings, Scheduling, Properties, Comments.
  2. Configure the processor according to the behavior you expect in your data flow.

    Make sure that you set all required properties, as you cannot start the processor until all mandatory properties have been configured.

  3. When you have finished configuring the options you need, save the changes by clicking Apply.

    The following properties are used for PutHDFS:

    Property Description Example value for ingest data flow

    Hadoop Configuration Resources

    Specify the path to the core-site.xml configuration file.

    Make sure that the default file system (fs, default.FS) points to the GCS bucket you are writing to.

    /etc/hadoop/conf.cloudera.core_settings/core-site.xml

    Kerberos Principal

    Specify the Kerberos principal (your username) to authenticate against CDP.

    srv_nifi-gcs-ingest

    Kerberos Password

    Provide the password that should be used for authenticating with Kerberos.

    password

    Directory

    Provide the path to your target directory in Google Cloud expressed in a GCS compatible path. It can also be relative to the path specified in the core-site.xml file.

    gs://your path/customer

    You can leave all other properties as default configurations.

    For a complete list of PutHDFS properties, see the processor documentation.

    If you want to use the PutGCSObject processor to store the data in Google Cloud Storage, you have to configure your processor to reference the controller service you configured before:

    If you want to move data to a different location, review the other use cases in the Cloudera Data Flow for Data Hub library.
