Question

我的流媒体工作正在获得error code 132。我已经在单节点（伪分布式）集群上成功测试了这个。它在某个实际集群中的reduce步骤中失败了。

注意：我不在任何地方获取error code 1。（错误代码1表明mapper / reducer代码本身出了问题）

Container killed by the ApplicationMaster.
Container killed on request. Exit code is 143
Container exited with a non-zero exit code 143

我还尝试将reducer代码放在try-catch块中，并在代码失败时打印异常（即静默失败）但catch块永远不会被执行而作业失败。

编辑：我正在使用AWS EMR来运行我的群集（EMR版本5.5.0）
