This page explains how to update a Dataproc Metastore service.

You can update your Dataproc Metastore service to change configuration settings, or to enable or disable optional features.

Before you begin

Required roles

To get the permission that you need to update a Dataproc Metastore service, ask your administrator to grant you the following IAM roles on your project, based on the principle of least privilege:

  • Grant full control of Dataproc Metastore resources (roles/metastore.editor)
  • Grant full access to all Dataproc Metastore resources, including IAM policy administration (roles/metastore.admin)

For more information about granting roles, see Manage access.

This predefined role contains the metastore.services.update permission, which is required to update a Dataproc Metastore service. You might also be able to get this permission with custom roles or other predefined roles.

For more information about specific Dataproc Metastore roles and permissions, see Dataproc Metastore IAM overview.

About updating a service

You can update the following Dataproc Metastore parameters.

  • Port number. Update the TCP port number of the Apache Thrift interface.
  • Service tier. Switch between the Developer service tier or Enterprise service tier. These tiers influence the capacity of the service.
  • Data Catalog sync. Toggle the Data Catalog sync feature on or off.
  • Maintenance window. Change the frequency of your maintenance window, including Day of week and Hour of day.
  • Kerberos. Enable or disable Kerberos authentication. If previously enabled, you can update your Kerberos configuration files.
  • Hive metastore configurations. Update the location of your Hive warehouse directory.
  • Auxiliary version config. Enable, disable, or add additional auxiliary versions.
  • Labels. Add or remove optional labels that describe your metadata.

Update a service

Before running an update, note the following considerations:

  • You can only run a single update job at a time (for each Dataproc Metastore service).
  • You can update multiple parameters in a single update job.
  • You can still use your Dataproc Metastore while it's being updated.

When the update succeeds, Dataproc Metastore automatically enters an active state. If the update fails, then the Dataproc Metastore service rolls back to its previous healthy state.

The following instructions show you how to update a Dataproc Metastore service.

Console

  1. In the Google Cloud console, open the Dataproc Metastore page:

    Open Dataproc Metastore

  2. On the Dataproc Metastore page, click the service name of the service that you want to update.

    The Service detail page opens.

    Service detail page
  3. On the Configuration tab, click Edit.

    The Edit service page opens.

  4. Choose the values that you want to update for your service.

  5. Click Submit.

    Return to the Dataproc Metastore page, and verify that your service was successfully updated.

gcloud CLI

  1. To update a service, run the following gcloud metastore services update command:

    gcloud metastore services update SERVICE \
        --location=LOCATION \

Update the Hive Metastore warehouse config

If your Hive warehouse directory is on Cloud Storage, you should set a Metastore config override. This override sets your specific data warehouse as the default warehouse directory for Dataproc Metastore.

Before you set this override, make sure that your Dataproc Metastore service has object read and write permissions to access the warehouse directory. For more information, see Hive warehouse directory.

The following instructions show you how to update a Hive Metastore config override.

Console

  1. In the Google Cloud console, open the Dataproc Metastore page:

    Open Dataproc Metastore

  2. On the Dataproc Metastore page, click the service name of the service want to update.

    The Service detail page opens.

  3. On the Configuration tab, click Edit.

    The Edit service page opens.

  4. In the Metastore config overrides, enter the following:

    • Key: Enter the following value: hive.metastore.warehouse.dir.
    • Value: The Cloud Storage location of your warehouse directory. For example: gs://my-bucket/path/to/location
  5. Click Submit.

    Return to the Dataproc Metastore page, and verify that your service was successfully updated.

gcloud

  1. To update a service, run the following gcloud metastore services update command:

    gcloud metastore services update SERVICE \
        --location=LOCATION \
        --update-hive-metastore-configs="hive.metastore.warehouse.dir=CUSTOMER_DIR"
    

    Replace the following:

    • SERVICE: The name of your Dataproc Metastore service.
    • LOCATION: The Google Cloud region that your Dataproc Metastore service resides in.
    • CUSTOMER_DIR: The Cloud Storage location of your warehouse directory. For example: gs://my-bucket/path/to/location
