Subject [jira] [Updated] (SPARK-17720) Static configurations in SQL
Date Mon, 03 Oct 2016 18:24:20 GMT

     [ https://issues.apache.org/jira/browse/SPARK-17720?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Reynold Xin updated SPARK-17720:
--------------------------------
    Description: 
Spark SQL has two kinds of configuration parameters: dynamic configs and static configs. Dynamic
configs can be modified after Spark SQL is launched (after SparkSession is setup), whereas
static configs are immutable once the service starts.

It would be useful to have this separation and tell users if the user tries to set a static
config after the service starts.
