For secure and non-secure clusters, with Hive security authorization enabled, the Hive service check may fail. Hive security authorization may not be configured properly.
Solution
Two workarounds are possible. Using Ambari Web, in HiveConfigsAdvanced:
Disable hive.security.authorization, by setting the hive.security.authorization.enabled value to false.
or
Properly configure Hive security authorization. For example, set the following properties:
Table 11.1. Hive Security Authorization Settings
Property Value hive.security.authorization.manager
org.apache.hadoop.hive.ql.security.authorization.StorageBasedAuthorizationProvider
hive.security.metastore.authorization.manager
org.apache.hadoop.hive.ql.security.authorization.StorageBasedAuthorizationProvider
hive.security.authenticator.manager
org.apache.hadoop.hive.ql.security.ProxyUserAuthenticator
