我在hadoop上通过mahout运行kmeans clustering时出错，检查错误日志后，我认为可能是hadoop本机库引起的，但是当我自己重新编译hadoop，然后去运行作业时，它总是扔掉hs_err_pid*.log，其内容如下：strong text

    Is there anyone can help me or give me some advice?

这实际上与 Hadoop 或 Mahout 无关。JVM 本身崩溃了。这是 JVM 中的错误，或者是您的 JVM 安装问题。再试一次，和/或重新安装 Java。

我可以帮助你理解这个问题，如下所示：

如果您在堆栈上工作并看到堆栈中使用 Hadoop 库进行的最后一次调用如下所示：

org.apache.hadoop.util.NativeCodeLoader

现在，如果您查看此处的源代码，您将看到代码正在尝试加载 Hadoop 库，如下所示：

41   try {
42      System.loadLibrary("hadoop");
43      LOG.info("Loaded the native-hadoop library");
44      nativeCodeLoaded = true;
45    } catch (Throwable t) {
46      // Ignore failure to load
47      LOG.debug("Failed to load native-hadoop with error: " + t);
48      LOG.debug("java.library.path=" + System.getProperty("java.library.path"));
49    }

现在，如果您查看调用堆栈，您将看到 Java 运行时尝试加载库然后发生崩溃的完全相同的事情：

Java.lang.ClassLoader$NativeLibrary.load(Ljava/lang/String;)V+0
java.lang.ClassLoader.loadLibrary0(Ljava/lang/Class;Ljava/io/File;)Z+300
java.lang.ClassLoader.loadLibrary(Ljava/lang/Class;Ljava/lang/String;Z)V+347
java.lang.Runtime.loadLibrary0(Ljava/lang/Class;Ljava/lang/String;)V+54
java.lang.System.loadLibrary(Ljava/lang/String;)V+7
org.apache.hadoop.util.NativeCodeLoader.<clinit>()V+25

所以这个问题与 Java 运行时完全相关，你无能为力。您肯定可以记录此错误并继续尝试再次测试您的代码。这样的问题可能会不时发生，您只需继续进行下一个。
