finkcdc同步到clickhouse，报异常org.apache.flink.connector.clickhouse.internal.executor.ClickHouseExecutor [] - ClickHouse executeBatch error, retry times = 1 ru.yandex.clickhouse.except.ClickHouseUnknownException: ClickHouse exception, code: 1002, host: 10.240.1.155, port: 8123; Connection pool shut down image image 然后线程池一直阻塞WAITING TIMED_WAITING image 最后导致tsakmanager进程挂掉

我想知道该怎么解决这个问题

  1. 报错是发生的数据发送给server的过程中，但从上文异常内容找不到Http Pool shut down的具体原因；
  2. 你可以看下ClickHouse Server和Flink端的详细日志排查下；
