sbt - Hadoop depends on two different versions of beanutils -


hadoop 2.4.0 depends on 2 different versions of beanutils, causing following error sbt-assembly:

[error] (*:assembly) deduplicate: different file contents found in following: [error] .ivy2/cache/commons-beanutils/commons-beanutils/jars/commons-beanutils-1.7.0.jar:org/apache/commons/beanutils/basicdynabean.class [error] .ivy2/cache/commons-beanutils/commons-beanutils-core/jars/commons-beanutils-core-1.8.0.jar:org/apache/commons/beanutils/basicdynabean.class

both of these dependencies transitive hadoop 2.4.0, confirmed using how access ivy directly, i.e. access dependency reports or execute ivy commands?

how can make sbt-assembly including hadoop 2.4.0?

update: requested, here build.sbt dependencies:

librarydependencies += "org.apache.hadoop" % "hadoop-client" % "2.4.0"  librarydependencies += "org.apache.spark" %% "spark-core" % "1.0.0"  % "provided" exclude("org.apache.hadoop", "hadoop-client")  resolvers += "akka repository" @ "http://repo.akka.io/releases/"  librarydependencies += "com.amazonaws" % "aws-java-sdk" % "1.7.8"  librarydependencies += "commons-io" % "commons-io" % "2.4"  librarydependencies += "javax.servlet" % "javax.servlet-api" % "3.0.1" % "provided"  librarydependencies += "com.sksamuel.elastic4s" %% "elastic4s" % "1.1.1.0"

the exclude hadoop needed because, out of box, spark includes hadoop 1, conflicts hadoop 2.

try add merge strategy build.sbt

like below

val meta = """meta.inf(.)*""".r  mergestrategy in assembly <<= (mergestrategy in assembly) { (old) =>   {     case pathlist("javax", "servlet", xs @ _*) => mergestrategy.last     case pathlist("javax", "activation", xs @ _*) => mergestrategy.last     case pathlist("org", "apache", xs @ _*) => mergestrategy.last     case pathlist("com", "esotericsoftware", xs @ _*) => mergestrategy.last     case pathlist("plugin.properties") => mergestrategy.last     case meta(_) => mergestrategy.discard     case x => old(x)   } }

javascript - RequestAnimationFrame not working when exiting fullscreen switching space on Safari -
