------------------------------------
Summary: Configuration object gets created for every task even if
not new file/jar is added
Key: SPARK-4612
URL: https://issues.apache.org/jira/browse/SPARK-4612
Project: Spark
Issue Type: Improvement
Components: Spark Core
Reporter: Tathagata Das
Assignee: Tathagata Das
https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/executor/Executor.scala#L337
creates a configuration object for every task that is launched, even if there
is no new dependent file/JAR to update. This is a heavy-weight creation that
should be avoided if there is not new file/JAR to update.
