> In the file  spark/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/jdbc/JdbcUtils.scala,we
have the method savePartition().We can create JDBC connection with each partition.But when
I insert data to my relational DB,it is blocked.I found that we commit once in a partition.Then
I changed it.I commit   
>  after executeBatch() and my code worked properly.I did not know how it performed in
NoSQL database,but it does have a problem in my relational DB.
