Description

The getClusterId method was added to Connection for delegation token based auth. This interface is InterfaceAudience.Public so it breaks client compatibility. Hbase connections builds fail with the latest 2.4.14-SNAPSHOT version and downstream applications relying on Connection interface will fail to work on these versions.
