------------------------------
Summary: Allow users to disable Jetty Spark UI in local mode
Key: SPARK-2100
URL: https://issues.apache.org/jira/browse/SPARK-2100
Project: Spark
Issue Type: Improvement
Reporter: DB Tsai
Since we're using Spark hadoop APIs in local mode for design time to explore
the first couple hundred lines of data in HDFS. Also, we use it in our tomcat
application, and starting a jetty UI will make our tomcat unhappy. In those
scenarios, Spark UI is not necessary, and wasting resource.
As a result, for local mode, users should be able to disable the spark UI.
Couple places I found that the jetty will be started.
In SparkEnv.scala
1) val broadcastManager = new BroadcastManager(isDriver, conf, securityManager)
2) val httpFileServer = new HttpFileServer(securityManager)
httpFileServer.initialize()
I don't know if broadcastManager is needed in local mode tho.
