> Using Hadoop credential provider API to store password
> ------------------------------------------------------
>
> Key: SPARK-24518
> URL: https://issues.apache.org/jira/browse/SPARK-24518
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.3.0
> Reporter: Saisai Shao
> Priority: Minor
>
> 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.
