Eric Feng updated YARN-5518:
----------------------------
Description:
This JIRA tracks changes to WebApps and web services/clients to support
HTTP_AND_HTTPS policy.
Currently WebApps/WebServers in Hadoop only supports HTTP_ONLY and HTTPS_ONLY
policies. This means that there will be a service interruption when the policy
is changed from HTTP_ONLY to HTTPS_ONLY.
The reason for this limitation is that org.apache.hadoop.yarn.webapp.WebApps
only supports one endpoint. However, the http server behind it does support
multiple endpoints. If support for multiple endpoints are added in WebApps, we
can add both HTTP and HTTPS endpoints to support HTTP_AND_HTTPS policy.
With this feature, switching from HTTP to HTTPS without service interruption
will be possible with the following two configuration changes:
1a. Changing policy from HTTP_ONLY to HTTP_AND_HTTPS;
(1b. Update client code to use HTTPS)
2. Changing policy form HTTP_AND_HTTPS to HTTPS_ONLY;
was:
Currently WebApps/WebServers in Hadoop only support HTTP_ONLY and HTTPS_ONLY
policy, which means there will be a service interruption when we change the
policy from HTTP_ONLY to HTTPS_ONLY.
The root cause of this limit is that org.apache.hadoop.yarn.webapp.WebApps
supports only one endpoint, but the http server(HttpServer2) behind it do
support multiple endpoints. So if we add multiple endpoints support in WebApps,
we can add both HTTP endpoint and HTTPS endpoint in all web servers in Hadoop,
i.e. support HTTP_AND_HTTPS policy. with this support, we will be able to
switch the web protocol from HTTP to HTTPS by 2 config changes without service
interruption:
1. change policy from HTTP_ONLY to HTTP_AND_HTTPS;
2. change policy form HTTP_AND_HTTPS to HTTPS_ONLY;
This JIRA tracks changes to WebApps and web services/clients to support
HTTP_AND_HTTPS policy.
