Talat UYARER created SPARK-21036:
------------------------------------

             Summary: Truncate action and writes should be in one transaction.
                 Key: SPARK-21036
                 URL: https://issues.apache.org/jira/browse/SPARK-21036
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.1.1, 2.1.0
            Reporter: Talat UYARER
            Priority: Minor


 When I use truncate option like this: spark.range(10).write.mode("overwrite").option("truncate", true).jdbc(url, "table_with_index", prop)

First table is truncated in a transaction later it will start write another transaction. This effects the data lost and found for a moment. 

This actions should be in same transaction.
