>                 URL: https://issues.apache.org/jira/browse/HADOOP-16079
>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: security
>    Affects Versions: 3.1.2, 3.2.1
>            Reporter: Steve Loughran
>            Assignee: Steve Loughran
>            Priority: Blocker
>             Fix For: 3.2.1, 3.1.3
>         Attachments: HADOOP-16079-001.patch
> The patch in HADOOP-15808 turns out not to be enough; Token.toString() fails if any token
in the service lists isn't known.
> If any JAR lists a class in META-INF/services/org.apache.hadoop.security.token.TokenIdentifier
which refers to a class which for any reason cannot load (e.g. it depends on a class which
is in a JAR that is not on the classpath), then the enumeration of all tokens and their supported
kinds will fail. This can surface in Token.toString(), but it will also break the RM token
renewal thread.
