[SPARK-12088][SQL]check connection.isClosed before calling connectionâ¦
In Java Spec java.sql.Connection, it has
boolean getAutoCommit() throws SQLException
Throws:
SQLException - if a database access error occurs or this method is called
on a closed connection
So if conn.getAutoCommit is called on a closed connection, a SQLException
will be thrown. Even though the code catch the SQLException and program can
continue, I think we should check conn.isClosed before calling
conn.getAutoCommit to avoid the unnecessary SQLException.
