Shixiong Zhu updated SPARK-17714: --------------------------------- Component/s: Spark Core > 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 > Components: Spark Core > Reporter: Weiqing Yang > Assignee: Shixiong Zhu > Fix For: 2.1.1, 2.2.0 > > > 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: >
