mysql5.6.x 是不支持吗？在本地可以连，但在程序里连不了。

show master status;
mysql-bin-changelog.139198 5292

telnet 10.40.0.109 3306 在本地也是可以进去的。
是什么原因呢？

` val db = "delta_db"

批查询是可用的

val mysqlConf = Map(
      "url" -> url,
      "driver" -> "com.mysql.jdbc.Driver",
      "user" -> user,
      "password" -> passwd,
      "dbtable" -> "(SELECT * FROM dlta_tab limit 10) as dlta_tab_tmp"
    )
    import org.apache.spark.sql.functions.col
    var df = spark.read.format("jdbc").options(mysqlConf).load()
    df = df.repartitionByRange(2, col("id"))
    df.show()
    df.write
      .format("delta").
      mode("overwrite").

      save("/tmp/datahouse/delta/batch_dlta_tab")
    spark.close()

因为我们走的是代理连mysql，所以比较慢，用原始连接设了连接时长就可以了，请问这个参数可以在这里设吗？还是需要改原代码，问题比较多，用的很坚难呀
