-----------------------------------------------
Summary: 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
Assignee: 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.
