Date Wed, 26 Nov 2014 01:43:12 GMT
Tathagata Das created SPARK-4612:
------------------------------------

             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.
