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.
