WebHCat provides external REST APIs for Hive. By default, the open-source community version uses the HTTP protocol.
MRS Hive supports the HTTPS protocol that is more secure, and enables switchover between the HTTP protocol and the HTTPS protocol.
The security mode supports HTTPS and HTTP, and the common mode supports only HTTP.
If the Components tab is unavailable, complete IAM user synchronization first. (On the Dashboard page, click Synchronize on the right side of IAM User Sync to synchronize IAM users.)
