Overview
The Hive Snap Pack supports Cloudera Data Platform authentication. You can use the Generic Hive Database Account to connect to the Hive database through the knox reverse proxy using the Workload user's credentials. The Cloudera Workload user credentials are used to authenticate against Knox reverse proxy and subsequently connect to the Hive database. The Knox reverse proxy hides the complex details for managing kerberos based authentication and authorization from the client.
Prerequisites
Valid Cloudera Workload user’s credentials.
Clouder instance.
This document provides details assuming you have an existing Data Hub Cluster in Cloudera Data Platform.
Locate Details in Cloudera
To validate your Generic Hive Database account in SnapLogic against the Clouder Knox reverse proxy, you must have the following details:
JDBC URL
JDBC Driver Class
Workload User name and password.
Log in to Cloudera Data Platform portal (https://sso.cloudera.com) or register yourself if you do not have an account.
The MyCloudera home page is displayed.Click your Profile icon and select Cloudera Data Platform. For example, Cloudera Data Platform US West. You will be redirected to the Clouderra Data Platform.
To demonstrate the procedure of accessing the details from CDP, we are using Cloudera Data Platform US West.Under Data Management, click the Management Console card.
Click Data Hub Clusters and select the Data Hub Cluster that is active and running. The list of hub clusters is displayed.
Under Cloudera Manager Info, click the Endpoints tab.
All services that are running on the CDP are displayed.Copy or make note of the JDBC URL of the Hive Server to use it in the Generic Hive Database Account.
Navigate to User Management. Click the <user> and select Profile and make note of the Workload credentials.
Configuring Generic Hive Database Account with Cloudera
Drag the Hive Execute Snap.
Add the Generic Hive Database Account to the Snap.
Enter the Username and Password of your Cloudera workload. (Refer to Step 7 above.)
Enter the JDBC URL of the Hive Server.
Note: By default, the raw URL is got from Cloudera; you have to enter the port number right after the domain and update the SSL value from true to 1. 0 is false and 1 is true. (Refer to Step 6 above for the raw URL format.)
If the cluster is SSL-enabled, the default value of SSL is true in the JDBC URL; replace it with 1.Enter the Site number as 443.
If the SSL is enabled on the Hive server, leave SSL as true. If the SSL is not enabled on the server, enter SSL as 0 or 1.
For example,jdbc:hive2://data-hub-cluster-1-gateway.snap-tea.j7vi-6hdh.a3.cloudera.site:443/;ssl=1;transportMode=http;httpPath=data-hub-cluster-1/cdp-proxy-api/hive
Upload the JDBC Driver. You can download the latest JDBC Hive driver from here.
Specify the JDBC Driver Class as
