知道了原因以后就好办了,hadoop的mapreduce作业启动的时候,都会读取jobConf中的配置(hadoop-site.xml),只要在该配置文件中将每个task的jvm进程中的-Xmx所配置的java进程的max heap size加大,就能解决这样的问题: <property> <name>mapred.child.java.opts</name> <value>-Xmx1024m</value> </property> PS:该选...
I have the following syntax to merge two datasets. I expect that the resulting dataset (test1) contains 5 cases with 4 of them (2 to 5) a value in variable set2. The result I am getting is dataset tes... Unable to read XML File stored in GCS Bucket ...
Good about Java: friendly syntax, memory management[GC can collect unreferenced memory resources], object-oriented features, portability. Stack Stores method invocations, local variables(include object reference, but the object itself is still stored in heap). If you look at the stack trace, the t...
synchronized在java中可以修饰方法,从而简单地实现函数的同步调用。在系统ets开发中,如何简单实现该功能 ArkTS类的方法是否支持重载 如何将类Java语言的线程模型(内存共享)的实现方式转换成在ArkTS的线程模型下(内存隔离)的实现方式 以libstd为例,C++的标准库放在哪里了,有没有打到hap包中 如何开...

Use -Xms to specify the initial Java heap size Use -Xss to set the Java thread stack size For example, use this syntax to specify the amount of memory the JVM should use: -Xms64m or -Xms64M // 64 megabytes (initial memory) -Xmx1g or -Xmx1G // 1 gigabyte (maximum memory) A comp...
