seatunnel部署遇到的一些问题及总结

环境：

jdk1.8

seatunnel2.3.3

需求：

想实现MYSQL到CLICKHOUSE同步

问题：

问题一：执行seatunnel本地案例提示如下

且在 apache-seatunnel-2.3.3/connectors/seatunnel中存在FakeSource的connector-fake-2.3.3.jar包

原因：缺少包 在安装目录/usr/local/seatunnel/apache-seatunnel-2.3.3/lib下加入如下包（可以通过maven仓库获取）

报错二:Caused by: java.lang.NoSuchMethodError: 'java.lang.String com.mysql.cj.CharsetMapping.getStaticJavaEncodingForMysqlCharset(java.lang.String)

 解决方案：

之前用的mysql驱动mysql-connector-java-8.0.25.jar  需要升级到   mysql-connector-java-8.0.30.jar

问题三：Caused by: org.apache.seatunnel.engine.common.exception.JobDefineCheckException: 'MySQL-CDC' source don't support off-line job

问题四：mysql-cdc不支持离线模式 job.mode = "BATCH"，需要改成  job.mode = "STREAMING"

env {
        execution.parallelism = 1
        job.mode = "STREAMING"
        checkpoint.interval = 2000
}
source {
        MySQL-CDC {
        base-url = "jdbc:mysql://192.168.85.128:3307/gisqbpm"
        username = "root"
        password = "wxy123456"
        table-names = ["gisqbpm.test"]
   }
}
sink {
      Clickhouse {
                host = "192.168.85.128:8123"
                database = "gisqbpm"
                table = "test"
                username = "default"
                password = "wxy123456"
    }
}
