Subject [jira] [Comment Edited] (YARN-2554) Slider AM Web UI is inaccessible if HTTPS/SSL is specified as the HTTP policy

----------------------------------------------------------

I want to raise the issue again since the issue affects other application which runs on YARN.
Actually, I see this problem when we run Spark job on Yarn.
Spark launches Spark context web UI with custom SSL certificate when we enable SSL with "spark.ssl.trustStore"
and "spark.ssl.keyStore" properties. In this case, Yarn web proxy cannot connect the Spark
context web UI since the web proxy cannot verify the SSL cert ("javax.net.ssl.SSLHandshakeException:
sun.security.validator.ValidatorException: PKIX path building failed"  error is returned).


We should add an option to set SSL trust store to Yarn RM web proxy. I added the updated patch,
and this patch lets web proxy use an SSL custom trust-store if it is configured in ssl-client.xml

> If the HTTP policy to enable HTTPS is specified, the RM and AM are initialized with SSL
listeners.  The RM has a web app proxy servlet that acts as a proxy for incoming AM requests.
 In order to forward the requests to the AM the proxy servlet makes use of HttpClient.  However,
the HttpClient utilized is not initialized correctly with the necessary certs to allow for
successful one way SSL invocations to the other nodes in the cluster (it is not configured
to access/load the client truststore specified in ssl-client.xml).   I imagine SSLFactory.createSSLSocketFactory()
could be utilized to create an instance that can be assigned to the HttpClient.
> The symptoms of this issue are:
> AM: Displays "unknown_certificate" exception
> RM:  Displays an exception such as "javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException:
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable
to find valid certification path to requested target"
