我尝试了一下，把半角冒号换成全角冒号，错误提示如下：
22/07/29 07:51:42 WARN PDClient: failed to get member from pd server.
2022/7/29 15:51:42 com.pingcap.tikv.exception.TiKVException: Failed to build NettyChannelBuilder
加个空格的错误：
java.lang.IllegalArgumentException: Illegal character in authority at index 7: http://basic-pd.tidb-cluster: 2379
似乎不是因为半角全角或者空格的问题引起的：
22/07/27 23:15:56 WARN TiSparkTeleInfo$: Failed to qet PD version For input string: “2379,192.168.3.222:23379,192.168.3.223:2379”
