Sean Busbey commented on HBASE-20047: ------------------------------------- agreed. if we're concerned about performance here, make sure all the concats are done via StringBuilder.append. If we're not so concerned, then {{javac}} ought to turn one big block of + operators into a StringBuilder internally anyways, so just use them directly. > 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 > Priority: Minor > Labels: beginner > Attachments: HBASE-20047.master.v0.patch > > > 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:java} > 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. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
