[jira] [Created] (SPARK-23186) Loading JDBC Drivers should be syncronized

Dongjoon Hyun created SPARK-23186:
-------------------------------------

             Summary: Loading JDBC Drivers should be syncronized
                 Key: SPARK-23186
                 URL: https://issues.apache.org/jira/browse/SPARK-23186
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.2.1
            Reporter: Dongjoon Hyun


Since some JDBC Drivers have class initialization code to call `DriverManager`, we need to synchronize them to avoid potential deadlock situation like STORM-2527.
