flink 1.14.3集群jar部署Recovery is suppressed by NoRestartBackoffTimeStrategy

flink程序在开发环境已经运行成功的情况下，部署到独立的flink集群（start-cluster）中，可能遇到不能正常运行的情况。

1. org.apache.flink.runtime.JobException: Recovery is suppressed by NoRestartBackoffTimeStrategy

没有指定重启策略，在本地部署时，不需要指定重启策略。

可以通过下面的代码指定重启策略

env.setRestartStrategy(RestartStrategies.fixedDelayRestart(
                3, // 尝试重启的次数
                Time.of(10, TimeUnit.SECONDS) // 间隔
        ));

失败率重启

val env = ExecutionEnvironment.getExecutionEnvironment()
env.setRestartStrategy(RestartStrategies.failureRateRestart(
  3, // 一个时间段内的最大失败次数
  Time.of(5, TimeUnit.MINUTES), // 衡量失败次数的是时间段
  Time.of(10, TimeUnit.SECONDS) // 间隔
))

不重启

val env = ExecutionEnvironment.getExecutionEnvironment()
env.setRestartStrategy(RestartStrategies.noRestart())

2. getSerializableListState(Ljava/lang/String;)

在本地调试正常，上传到集群环境出现该错误提示：

org.apache.flink.api.common.state.OperatorStateStore.getSerializableListState(Ljava/lang/String；)

主要原因是版本不一致造成的，pom.xml文件中添加了scala 2.11的依赖包，集群环境是2.12版本，所以导致执行失败。

3. No ExecutorFactory found to execute the application

本地调试的时候，出现该错误，缺少依赖。

<flink.version>1.14.3</flink.version>

<dependency>
            <groupId>org.apache.flink</groupId>
            <artifactId>flink-clients_2.12</artifactId>
            <version>${flink.version}</version>
        </dependency>

4. 可以打包在集群环境运行的参考pom.xml

 打包时，对于集群环境中已经存在的jar，打包时采用provided，避免冲突。
