Flink job executed failed

Error message

Flink job executed failed

What it means

CommandExecuteException thrown by FlinkTaskExecuteCommand.execute when FlinkExecution.execute() (building and launching the Flink job) throws any exception. It is a generic wrapper meaning 'the Flink job failed to execute'; the actual cause is attached as the exception cause.

Solutions

1. Read the full stack trace / cause of the CommandExecuteException for the real failure
2. Verify the target Flink cluster is reachable and matches the configured master/deploy mode
3. Validate the job config (env, source, sink sections) and ensure plugin jars are installed in the Flink lib/connector directory

// validate config and cluster before executing
new ConfigValidator().validate(config);
if (!clusterHealthCheck(masterUrl)) {
    throw new IllegalStateException("Flink cluster unreachable");
}

try {
    command.execute();
} catch (CommandExecuteException e) {
    log.error("Flink job failed, root cause:", e.getCause());
    throw e;
}

When it happens

Trigger: Any failure during FlinkExecution.execute — invalid job config after env merging, Flink pipeline construction errors, plugin initialization failures, cluster submission failures — surfacing as this wrapper in the command layer.

Common situations: Unreachable or misconfigured Flink cluster; missing plugin jars on the classpath; invalid env config (parallelism, job name); errors thrown deeper in sink/source processors.
