Weiqing Yang created SPARK-17714:
------------------------------------
Summary: ClassCircularityError is thrown when using
org.apache.spark.util.Utils.classForName
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:
