["Saisai Shao (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SPARK-24518?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Saisai Shao updated SPARK-24518:
--------------------------------
    Description: 
Current Spark configs password in a plaintext way, like putting in the configuration file or adding as a launch arguments, sometimes such configurations like SSL password is configured by cluster admin, which should not be seen by user, but now this passwords are world readable to all the users.

Hadoop credential provider API support storing password in a secure way, in which Spark could read it in a secure way, so here propose to add support of using credential provider API to get password.
