我已经完成了前面提到的问题，并尝试了那里提到的解决方案。它对我来说没有用。运行将文档目录转换为序列文件时，它是相同的Java堆空间错误。 creating vectors from text
我尝试使用export MAHOUT_HEAPSIZE=10000M更改mahout堆大小。这没有用。在某个地方，我看到它应该检查哪个进程正在消耗内存或者堆空间耗尽了什么。为此，我在运行mahout工作之前运行了jps。这并没有给我提供进程ID或提及here的任何内容。也许我做得不对。

OpenJDK 64-Bit Server VM warning: You have loaded library /opt/hadoop/2.4.0/lib/native/libhadoop.so.1.0.0 which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
