Haohui Mai commented on HDFS-7959:
----------------------------------
bq. Besides, not all the components in the current jetty log is actually useful
(e.g. response code)
The response code is useful in terms of debugging authentication issues (401 /
500 / etc.). Maybe it is a good idea to keep them?
bq. It is probably a good idea to sanitize the tokens in the request URI before
logging. I will update the patch.
I think that the right fix is to move delegation token from the URL to the
header. Logging requests seem really general and it might be a bad idea to mix
it with the requirements of the application layers.
