Shell.getUlimitMemoryCommand介绍

[英]Get the Unix command for setting the maximum virtual memory available to a given child process. This is only relevant when we are forking a process from within the Mapper or the Reducer implementations. Also see Hadoop Pipes and Hadoop Streaming. It also checks to ensure that we are running on a nix platform else (e.g. in Cygwin/Windows) it returns null.
[中]获取Unix命令，用于设置给定子进程可用的最大虚拟内存。这仅在我们从Mapper或Reducer实现中派生流程时才相关。另请参见Hadoop管道和Hadoop流。它还会检查以确保我们在nix平台上运行，否则（例如在Cygwin/Windows中）它会返回[$0$]。
