-------------------------------------
Summary: StreamingTab calls public APIs in Spark core that expose
shaded classes
Key: SPARK-9261
URL: https://issues.apache.org/jira/browse/SPARK-9261
Project: Spark
Issue Type: Bug
Components: Streaming
Affects Versions: 1.5.0
Reporter: Marcelo Vanzin
Priority: Minor
There's a minor issue in {{StreamingTab}} that has hit me a couple of times
when building with maven.
It calls methods in {{JettyUtils}} and {{WebUI}} that expose Jetty types
(namely {{ServletContextHandler}}). Since Jetty is now shaded, it's not safe to
do that, since when running unit tests the spark-core jar will have the shaded
version of the APIs while the streaming classes haven't been shaded yet.
This seems, at the lowest level, to be a bug in scalac (I've run into this
issue in other modules before), since the code shouldn't compile at all, but we
should avoid that kind of thing in the first place.
