--------------------------------
Summary: Support removing Hive Metastore password from Hive
configuration
Key: AMBARI-18176
URL: https://issues.apache.org/jira/browse/AMBARI-18176
Project: Ambari
Issue Type: Improvement
Components: ambari-server
Affects Versions: 2.2.0
Reporter: Bing Li
Based on Hive wiki:
https://cwiki.apache.org/confluence/display/Hive/AdminManual+Configuration#AdminManualConfiguration-RemovingHiveMetastorePasswordfromHiveConfiguration
Hive supports to use a CredentialProvider to handle storing/retrieval of
passwords from 0.14.0 (Hadoop version should be 2.6.0+).
Current Ambari doesn't support it, because we can't delete a default property
or set an empty value to a property on UI.
In order to improve this,
1. Ambari could have the user to specify whether to use a Hadoop credential
store for the password
2. If the user selects yes, then Ambari should show an input field for
providing the credential file location
3. The password field can stay, but depending on whether the credential store
is selected or not, the password should be written to either the credential
store or the hive-site.xml directly (this takes care of the user changing the
password).
