Cloud Dataproc Hive WebHCat Component

You can install additional components when you create a Dataproc cluster using the Optional Components feature. This page describes the Hive WebHCat component.

The Hive WebHCat component provides a REST API for HCatalog. The REST service is available on port 50111 on the cluster's first master node.

Install the component

Install the component when you create a Dataproc cluster. Components can be added to clusters created with Dataproc version 1.3 and later.

See Supported Cloud Dataproc versions for the component version included in each Dataproc image release.

gcloud command

To create a Dataproc cluster that includes the Hive WebHCat component, use the gcloud dataproc clusters create cluster-name command with the --optional-components flag (using image version 1.3 or later).

gcloud dataproc clusters create cluster-name \
    --optional-components=HIVE_WEBHCAT \
    --image-version=1.3 \
    ... other flags

REST API

The Hive WebHCat component can be specified through the Dataproc API using SoftwareConfig.Component as part of a clusters.create request.
