Ayush Saxena commented on HDFS-15136:
-------------------------------------
Thanx [~prasad-acit] for the report and fix.
Instead of entire trace, you can just change to have just the message, that
would suppress the logging.
The changes in the UT seems unrelated, doesn't verify changes done here, We can
probably remove them.
For changing the log statement use the sl4j semantics
> In secure mode when Cookies are not set in request header leads to exception
> flood in DEBUG log
