Shuai Lin created SPARK-17802:
---------------------------------
Summary: Lots of "java.lang.ClassNotFoundException:
org.apache.hadoop.ipc.CallerContext" In spark logs
Key: SPARK-17802
URL: https://issues.apache.org/jira/browse/SPARK-17802
Project: Spark
Issue Type: Improvement
Components: Spark Core
Reporter: Shuai Lin
Priority: Minor
SPARK-16757 sets the hadoop {{CallerContext}} when calling hadoop/hdfs apis to
make spark applications more diagnosable in hadoop/hdfs logs. However, the
{{CallerContext}} is only added since hadoop 2.8. So each time
{{utils.CallerContext.setCurrentContext()}} is called (e.g when a task is
created), a "java.lang.ClassNotFoundException:
org.apache.hadoop.ipc.CallerContext"
error is logged.
We should improve this so it's only logged once.
