[Spark-20044][Web UI] Support Spark UI behind front-end reverse proxy using
a path prefix
## What changes were proposed in this pull request?
Allow to run the Spark web UI behind a reverse proxy with URLs prefixed by
a context root, like www.mydomain.com/spark. In particular, this allows to
access multiple Spark clusters through the same virtual host, only
distinguishing them by context root, like www.mydomain.com/cluster1,
www.mydomain.com/cluster2, and it allows to run the Spark UI in a common cookie
domain (for SSO) with other services.
## How was this patch tested?
New HTML Unit tests in MasterSuite
Manual UI testing for master, worker and app UI with an nginx proxy
Spark config:
spark.ui.reverseProxy=true
spark.ui.reverseProxyUrl=/path/to/spark/
nginx config:
server {
listen 9000;
set $SPARK_MASTER http://<spark-host>:8080;
location ~ ^(?<prefix>/path/to/spark$) {
return 302 $scheme://$host:$server_port$prefix/;
}
location ~ ^(?<prefix>/path/to/spark)(?<local_path>/.*) {
rewrite ^ $local_path break;
proxy_pass $SPARK_MASTER;
proxy_redirect $SPARK_MASTER $prefix;
}
}
