Start Hive on an insecure cluster

If you want to use Apache Hive for a quick test, you can do so using Hive default authorization mode, assuming you are on an insecure cluster (no Kerberos or Ranger policies). In default authorization mode, only user hive can access Hive. Steps to start the Hive shell, not to be mistaken with the Hive CLI that CDP does not support, include how to log into a cluster.

In CDP Public Cloud, in Environments > your environment > Data Lakes > your data lake, in the Data Lake Cluster tab, click CM-UI.
In Cloudera Manager, click Hosts > All Hosts.
Make a note of the IP address or host name of a node in your cluster, for example myhost-vpc.cloudera.com.
Use ssh to log into the cluster.
For example:
```
ssh myhost-vpc.cloudera.com
```
Type hive to start Hive from the command line.

Enter Hive queries.

SHOW DATABASES;

CREATE TABLE students (name VARCHAR(64), age INT, gpa DECIMAL(3,2));

INSERT INTO TABLE students VALUES ('fred flintstone', 35, 1.28), ('barney rubble', 32, 2.32);
