Arpit Agarwal commented on HDFS-10676:
--------------------------------------
Thanks for submitting the patch [~hanishakoneru].
Two quick comments:
# It looks like we need separate metrics for generateEncryptedKey and
warmUpEncryptedKeys.
# The metric should be a {{MutableQuantiles}} so we can get latency percentiles.
Also tagging [~xyao] who understands this part of the code much better.
