Error:在程序中无法处理的错误,表示运行应用程序中出现严重错误。 主要是VirtualMachineError(虚拟机错误): OutOfMemoryError:内存溢出。其中内存溢出又分为 java.lang.OutOfMemoryError: Java heap space java.lang.OutOfMemoryError: unable to create new native thread java.lang.OutOfMemoryError: PermGen space(...
我感觉 你内存 吃不下了，我建议你可以看看 启动脚本，如果里面有发现-Xmx 这种字段，你可以适当调大一点，就是 你要让mapreduce进行处理的时候，jvm内存吃不下这么多东西，你调大这个参数可以试试 建议重装系统
Java heap space或GC overhead limit exceeded或频繁FullGC 原因 直接原因:JVM堆空间不足,RM进程内部对象无法获取到足够的资源,并且在抛出OOM之前已经进行过一轮或多轮FullGC回收了失效的对象,仍无法获取足够的堆空间用于分配。 原因分析:RM有很多常驻对象(不能被JVM回收的对象),包括集群、队列(queue)、应用、执行...
