-----------------------------------
Summary: AuthenticationTokenIdentifier should provide a toString
Key: HBASE-20047
URL: https://issues.apache.org/jira/browse/HBASE-20047
Project: HBase
Issue Type: Improvement
Components: Usability
Reporter: Sean Busbey
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:
{code}
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_u...@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.
