HI,

I am facing issue with ES hadoop spark, Exception trace below. I dont find any ES-hadoop or spark connector for scala 2.11. Any pointer ?

I am using elasticsearch-hadoop with 2.3.3 and scala version 2.11.7 everywhere

libraryDependencies += "org.elasticsearch" % "elasticsearch" % "2.3.4

Output of below command

sbt "inspect tree clean" | grep 'org.scala-lang'  
[info] | +-_:ivyScala = Some(IvyScala(2.11.7,2.11,List(),true,false,false,org.scala-lang))
