Ajay Kumar commented on HADOOP-15441:
-------------------------------------
Since log message is parametrized it will not be evaluated if logging level is
not DEBUG.

> After HADOOP-14987, encryption zone operations print unnecessary INFO logs

> It looks like after HADOOP-14987, any encryption zone operations prints extra
> INFO log messages as follows:
> {code:java}
> $ hdfs dfs -copyFromLocal /etc/krb5.conf /scale/
> 18/05/02 11:54:55 INFO kms.KMSClientProvider: KMSClientProvider for KMS url:
> https://hadoop3-1.example.com:16000/kms/v1/ delegation token service:
> kms://[email protected]:16000/kms created.
> {code}
> It might make sense to make it a DEBUG message instead.
