Hello,
I have a piece of code that runs inside Spark Streaming and tries to get
some data from a RESTful web service (that runs locally on my machine). The
code snippet in question is:
Client client = ClientBuilder.newClient();
WebTarget target =
Your guess is right, that there are two incompatible versions of
Jersey (or really, JAX-RS) in your runtime. Spark doesn't use Jersey,
but its transitive dependencies may, or your transitive dependencies
may.
I don't see Jersey in Spark's dependency tree except from HBase tests,
which in turn

I'd take a look with 'mvn dependency:tree' on your own code first.
Maybe you are including JavaEE 6 for example?
For reference, my complete pom.xml looks like:
project xmlns=http://maven.apache.org/POM/4.0.0; xmlns:xsi=
It seems like YARN depends an older version of Jersey, that is 1.9:

When I've modified my dependencies to have only:
dependency
groupIdcom.sun.jersey/groupId
artifactIdjersey-core/artifactId
version1.9.1/version
That could well be it -- oops, I forgot to run with the YARN profile
and so didn't see the YARN dependencies. Try the userClassPathFirst
option to try to make your app's copy take precedence.
The second error is really a JVM bug, but, is from having too little
memory available for the unit tests.
Sean,
Thanks a lot for the important information, especially userClassPathFirst.
Cheers,
Emre
