Takanobu Asanuma commented on HDFS-15969:
-----------------------------------------
The following is an example of the token information.
{noformat}
Created token for tasanuma: HDFS_DELEGATION_TOKEN owner=tasanuma,
renewer=JobTracker, realUser=, issueDate=1620293228047, maxDate=1620898028047,
sequenceNumber=1, masterKeyId=2 on ha-hdfs:ha-nn-uri-0
{noformat}
I have seen this information in several other logs as well. I don't think it
has ever been considered sensitive in the Hadoop community. Given the impact on
existing users, we may want to keep it as INFO level.
