Haohui Mai commented on HADOOP-10252:
-------------------------------------
My concern is that it might not solve the HBase problem completely. Recently
{{HttpServer}} has gone through major surgeries for HTTPS support. For obvious
reason the deprecated code path is not very well tested.
I have spent reasonable amount of time to test the current code paths of the
{{HttpServer}} in NN / DN / JN / SNN in various configuration. In my opinion
the approach that HBASE-10336 takes might be a safer bet.
