RE: spark-core in a servlet

[Anton Brazhnyk]

Check for the dependencies. Looks like you have a conflict around servlet-api 
jars.
Maven's dependency-tree, some exclusions and some luck :) could help.

Subject: spark-core in a servlet

Hi,


I want to use spark-core inside of a HttpServlet. I use Maven for the
build task but I have a dependency problem :-(

I get this error message:

ClassCastException:
com.sun.jersey.server.impl.container.servlet.JerseyServletContainerInitializer
cannot be cast to javax.servlet.ServletContainerInitializer

When I add this exclusions it builds but than there are other classes
not found at runtime:

  
 org.apache.spark
 spark-core_2.11
 1.2.1
 

   org.apache.hadoop
   hadoop-client


   org.eclipse.jetty
   *

 
  


What can I do?


Thanks a lot!,

Ralph

I am not sure if this could be causing the issue but spark  is compatible
with scala 2.10.
Instead of spark-core_2.11 you might want to try spark-core_2.10
