It seems a project configuration error, as once you import the lib, it should be in the classpath.
Maybe your IDE is causing the problem. Try to compile and launch the application through sbt to see if the problem persists.

Hi
I am getting the same error.. sbt based compilation went through successfully. Please help solve this

This seems to happen when the application is running. Can you provide details on the launch environment and the scripts/arguments you used?
from spark-hbase-connector.
@balaji-krishnan72 you may bundle all libs (except spark-core) into your result jar. I've the same issue today. This may be done by sbt-assembly
plugin, ex.:
In project/plugins.sbt
add:
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.3")
And in build.sbt
:
//....
scalaVersion := "2.11.8"
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.6.0" % "provided"
libraryDependencies += "it.nerdammer.bigdata" % "spark-hbase-connector_2.10" % "1.0.3"
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", "google", xs @ _*) => MergeStrategy.last
case PathList("com", "esotericsoftware", xs @ _*) => MergeStrategy.last
case PathList("com", "codahale", xs @ _*) => MergeStrategy.last
case PathList("com", "yammer", xs @ _*) => MergeStrategy.last
case "about.html" => MergeStrategy.rename
case "META-INF/ECLIPSEF.RSA" => MergeStrategy.last
case "META-INF/mailcap" => MergeStrategy.last
case "META-INF/mimetypes.default" => MergeStrategy.last
case "plugin.properties" => MergeStrategy.last
case "log4j.properties" => MergeStrategy.last
case x => old(x)
}
}
//....
Then pack you jar by sbt assembly
from spark-hbase-connector.
I'm having the same issue. Compiles fine, then gives the error when run via spark-submit. Nothing passed into spark-submit besides the jar file:
spark-submit /path/to/jar/application.jar
from spark-hbase-connector.
