Description

Bellow is the code of using the string of current user object as the "user" value.

    entity.addPrimaryFilter("user", UserGroupInformation.getCurrentUser()
        .toString());

When we use kerberos authentication, it's going to output the full name, such as "zjshen/localhost@LOCALHOST (auth.KERBEROS)". It is not user friendly for searching by the primary filters. It's better to use shortUserName instead.
