> It'd be easier to debug things like MapReduce and Spark jobs if our AuthenticationTokenIdentifier
provided a toString method.
> For comparison, here's an example of a MapReduce job that has both an HDFS delegation
token and our delegation token:

> 18/02/21 20:40:06 INFO mapreduce.JobSubmitter: Kind: HBASE_AUTH_TOKEN, Service: 92a63bd8-9e00-4c04-ab61-da8e606068e1,
Ident: (org.apache.hadoop.hbase.security.token.AuthenticationTokenIdentifier@17)
> 18/02/21 20:40:06 INFO mapreduce.JobSubmitter: Kind: HDFS_DELEGATION_TOKEN, Service:
172.31.118.118:8020, Ident: (token for some_user: HDFS_DELEGATION_TOKEN owner=some_user@EXAMPLE.COM,
renewer=yarn, realUser=, issueDate=1519274405003, maxDate=1519879205003, sequenceNumber=23,
masterKeyId=9)
> {code}
> Stuff in TokenIdentifier is supposed to be public, so we should be fine to dump everything,
similar to Hadoop's AbstractDelegationTokenIdentifier.
