此外，我对"；标签"；对于这个问题，我不确定问题的来源是什么，所以如果有什么不相关的东西，请随时告诉我，这样我就可以删除它。如有任何帮助，我们将不胜感激！我正在AWS上处理一个ec2实例，所以我试图尽快解决它
没有什么可做的。SIGSEGV意味着JVM或在JVM上下文中运行的代码访问了不允许访问的内存。因此，JVM崩溃了。但它试图提供帮助，并指出问题可能在哪里：
V [libjvm.so+0xea8ba3]
这告诉我们JVM在libjvm.so中崩溃，libjvm.seo是JVM的核心部分。但这并不一定意味着故障在JVM中。让我们看看下面的堆栈跟踪：
V [libjvm.so+0xea8ba3]
J 3779 jdk.internal.misc.Unsafe.putInt(Ljava/lang/Object;JI)V java.base@11.0.9.1 (0 bytes) @ 0x00007ff247cf4a85 [0x00007ff247cf49c0+0x00000000000000c5]
j sun.misc.Unsafe.putInt(Ljava/lang/Object;JI)V+7 jdk.unsupported@11.0.9.1
j org.apache.spark.unsafe.Platform.putInt(Ljava/lang/Object;JI)V+6
这告诉我们ApacheSpark从方法org.apache.spark.unsafe.Platform.putInt(Ljava/lang/Object;JI)(最后两行(调用sun.misc.Unsafe。Unsafe允许在JVM不进行任何安全检查的情况下直接访问内存，因此得名(详细解释(。因此，如果ApacheSpark执行了一个不安全的调用，JVM因此崩溃，那么可以很安全地假设ApacheSpark在那里做了一些错误的事情。
我建议将其报告给ApacheSpark项目。因为无论您是犯了错误还是Apache Spark，都不应该因为试图访问不应该访问的内存而导致JVM崩溃。
