Xiaoyu Yao commented on HDFS-12738:
-----------------------------------

[~kihwal], on a pretty idle newly setup of 3 node clusters, I see around 3 
message/ minute. 
On production clusters, this message was seen at much higher rate.

> After enable HTTPS(SSL) for HDFS, the namenode log prints lots of SSL 
> renegotiate denied warnings. Not sure if this is caused by a similar reason 
> like YARN-6797. This ticket is opened to investigate and fix this.
