-----------------------------------
This is resolved now, right?
> ClassCircularityError is thrown when using

> Key: SPARK-17714
> URL: https://issues.apache.org/jira/browse/SPARK-17714
> Project: Spark
> Issue Type: Bug
> Reporter: Weiqing Yang
>
> This jira is a follow up to [SPARK-15857|
> https://issues.apache.org/jira/browse/SPARK-15857] .
> Task invokes CallerContext. SetCurrentContext() to set its callerContext to
> HDFS. In SetCurrentContext(), it tries looking for class
> {{org.apache.hadoop.ipc.CallerContext}} by using
> {{org.apache.spark.util.Utils.classForName}}. This causes
> ClassCircularityError to be thrown when running ReplSuite in master Maven
> builds (The same tests pass in the SBT build). A hotfix
> [SPARK-17710|https://issues.apache.org/jira/browse/SPARK-17710] has been made
> by using Class.forName instead, but it needs further investigation.
> Error:
