---------------------------------------

             Summary: Add support of MDC in spark driver logs.
                 Key: SPARK-31769
                 URL: https://issues.apache.org/jira/browse/SPARK-31769
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.0.0
            Reporter: Izek Greenfield


In order to align driver logs with spark executors logs, add support to log MDC 
state for properties that are shared between the driver the server executors 
(e.g. application name. task id) 
 The use case is applicable in 2 cases:
 # streaming
 # running spark under job server (in this case you have a long-running spark 
context that handles many tasks from different sources).

See also [SPARK-8981|https://issues.apache.org/jira/browse/SPARK-8981] that 
handles the MDC in executor context.
