为什么 Spark 作业失败 "Exit code: 52"

Question

我遇到过 Spark 作业失败的情况，跟踪如下：

我花了一段时间才弄明白 "exit code 52" 是什么意思，所以我把它放在这里是为了让可能正在搜索的其他人受益

退出代码 52 来自 org.apache.spark.util.SparkExitCode，它是 val OOM=52 - 即 OutOfMemoryError。这是有道理的，因为我也在容器日志中找到了这个：

16/02/16 17:09:59 ERROR executor.Executor: Managed memory leak detected; size = 4823704883 bytes, TID = 3226
16/02/16 17:09:59 ERROR executor.Executor: Exception in task 26.0 in stage 2.0 (TID 3226)

（请注意，我现在不确定问题是出在我的代码中还是由于 Tungsten 内存泄漏，但那是另一个问题）
