例如： clickhouse://host1:8123,host2:8123,host3:8123

您好，支持：
具体实现使用的是clickhouse-jdbc中的BalancedClickhouseDataSource

from flink-connector-clickhouse.

您好，我在flink sql中测试集群模式的url，结果失败了

输入的url是

CREATE TABLE (
   略
) WITH  (
  'connector' = 'clickhouse',
  'url' = 'clickhouse://192.168.0.1:30004,192.168.0.2:30004,192.168.0.3:30004',
  其他参数略
)

调试得到的url是clickhouse://null

INFO  org.apache.flink.connector.clickhouse.internal.connection.ClickHouseConnectionProvider [] - connecting to clickhouse://null, database gaofang

我猜测是org.apache.flink.configuration.ReadableConfig读取url的时候，如果遇到逗号分隔会存在异常。

明天我在调试一下，如果有结果的话，我提交一个PR修复一下

如果您能给出一些指导，那就更好不过啦 :）

另外搜索到两个相关问题的链接：

是因为我有一个自定义的Properties文件弄错了，所以读取到的为null。 😂

flink sql 1.15.1，测试集群模式url是没问题的。
