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

             Summary: Documentation for SPARK_HISTORY_OPTS unclear
                 Key: SPARK-8569
                 URL: https://issues.apache.org/jira/browse/SPARK-8569
             Project: Spark
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 1.4.0
            Reporter: Thomas Graves


Looking at the documentation for the Spark History server.  It has:

SPARK_HISTORY_OPTS      spark.history.* configuration options for the history 
server (default: none).

It is unclear to me the format in which I should specify the configuration 
options.  Is it a comma separated list, is it the same as JAVA_OPTS with -D. If 
its the same as the JAVA_OPTIONS is there any difference between these 
variables.

Note looking at the sbin/start_history_server.sh script it appears that you use 
-D in front of each conf.
