你好，因为业务逻辑变化，需要对线上在跑的flink任务重启，采用savapoint方式。
操作如下： # 查看yarn-application-id yarn application -list # 查看flink任务id flink list -t yarn-per-job -Dyarn.application.id=application_1617064018715_0097 # 带有保存点的停止任务 flink stop -t yarn-per-job -p hdfs:///user/chaos/flink/0097_savepoint/ -Dyarn.application.id=application_1617064018715_0097 d7c1e0231f0e72cbd709baa9a0ba6415 Savepoint completed. Path: hdfs://nameservice1/user/chaos/flink/0097_savepoint/savepoint-d7c1e0-96f5b07d18be # 从保存点中重启任务 flink run -t yarn-per-job -s hdfs://nameservice1/user/chaos/flink/0097_savepoint/savepoint-d7c1e0-96f5b07d18be -d -c xxx xxx.jar 遇到的问题： Service temporarily unavailable due to an ongoing leader election.
