property for credential provider.
URL: https://github.com/apache/hadoop/pull/5352
> Support custom property for credential provider path
> ----------------------------------------------------
>
> Key: HADOOP-18618
> URL: https://issues.apache.org/jira/browse/HADOOP-18618
> Project: Hadoop Common
> Issue Type: Improvement
> Components: common
> Affects Versions: 3.1.3
> Reporter: Surendra Singh Lilhore

> Hadoop allows the configuration of a credential provider path through the
> property "{*}hadoop.security.credential.provider.path{*}", and the
> {{Configuration#getPassword()}} method retrieves the credentials from this
> provider.
> However, using common credential provider properties for components like
> Hive, HDFS, and MapReduce can cause issues when they want to configure
> separate JCEKS files for credentials. For example, the value in the
> core-site.xml property file can be overridden by the hive-site.xml property
> file. To resolve this, all components should share a common credential
> provider path and add all their credentials.
> Azure storage supports account-specific credentials, and thus the credential
> provider should permit the configuration of separate JCEKS files for each
> account, such as the property
> "{*}fs.azure.account.credential.provider.path.<account>.blob.core.windows.net{*}".
> To accommodate this, the {{Configuration#getPassword()}} method should accept
> a custom property for the credential provider path and retrieve its value.
> The current default property can be overridden to achieve this.

> One Example is, Ambari
> [CustomServiceOrchestrator|https://github.com/apache/ambari/blob/trunk/ambari-agent/src/main/python/ambari_agent/CustomServiceOrchestrator.py#L312]
> service override the core-site.xml value for other component. This fix is
> very much needed for Ambari.
