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.
