Question

Error: Java heap space Container killed by the ApplicationMaster. Container killed on request. Exit code is 143.

The hadoop cluster has 3 machines, one of them is the master,others are datanode,the machine's RAM is 8G.

当我运行mapreduce时，得到错误：错误：Java堆空间容器被ApplicationMaster杀死。根据要求杀死容器。退出代码是143。

输入文件为500M，reduce数为4.当输入文件少于300M时，程序运行良好。
