Subject Re: Poll: Merge jira/http2 to master branch
Date Sun, 02 Dec 2018 20:33:48 GMT
Hi David,

The whole solr cluster must be consistent on what protocol they are going
to use (on Java 8):
- If all nodes start with HTTP/2 without TLS they will talk with each
others using h2c
- If all nodes start with HTTP/1.1 with TLS, they will talk with each
others using https.
