Apache zeppelin error

I have started apache zeppelin and running successfully in the configured port. While I am executing simple spark commands like 

sc.version
println(zeppelin)

I can just see "ERROR" string near run button without any error output on my console.

My error log :

ERROR [2016-10-21 22:38:05,837] ({pool-2-thread-6} Job.java[run]:189) - Job failed org.apache.spark.SparkException: Found both spark.driver.extraClassPath and SPARK_CLASSPATH.

Also I have mentioned the spark and java path in _zeppelin-env.sh_ file.

I know, this is quite a late answer, but for any one who faces similar issue.

Even I had similar issue, I had added some external dependency {com.twitter:algebird-core_2.11:0.11.0} in interpreter Mode for Spark. If any dependency added for any component, there might be a case that dependency is not compatible with Zeppelin Version or does not exist on remote. Once I removed that dependency, I started seeing other errors on Zeppelin console.

Just to make sure, "zeppelin.spark.printREPLOutput" is set to true, generally by default it is true only, but just to make sure!!
