[jira] [Created] (SPARK-14475) Propagate user-defined context from driver to executors

Eric Liang created SPARK-14475:
----------------------------------

             Summary: Propagate user-defined context from driver to executors
                 Key: SPARK-14475
                 URL: https://issues.apache.org/jira/browse/SPARK-14475
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
            Reporter: Eric Liang


It would be useful (e.g. for tracing) to automatically propagate arbitrary user defined context (i.e. thread-locals) from the driver to executors. We can do this easily by adding sc.localProperties to TaskContext.
