There are usually two ways to run Hadoop under Windows: One is to install a Linux operating system with a VM, which basically enables Hadoop to run in a full Linux environment, and the other is to emulate the Linux environment through Cygwin. The advantage of the latter is that it is easy to use and the installation process is simple. Let's take a look at the sec

?Introduction: VMware can run two or more windows, DOS, and Linux systems simultaneously on an individual local laptop machine. VMware uses a completely different concept than a "multi-boot" system. A multi-boot system can only run one system at a time, and the machine needs to be restarted when the system switches. VMware is truly "simultaneous" running, with multiple operating systems on the main system platform, just as the standard

First, let's take a look at the problem here, so as not to forget it. If you have time, you can get a detailed tutorial to play. The online tutorial is either an old version or an old version, or you just didn't say it to the point. 1. Disable IPv6 Configuration on the server. 2.if winutils.exe is not found, the system variable cannot be set with hadoop_home. environment variables can be directly set in the program, saving system configuration and making it easier.

see that there are two differences, one is the difference between Java commands, and the other is classpath. Place the breakpoint first:(1) Breakpoints for Java commands:Yarnrunner.java 390 Lines (cdh5.0 Hadoop2.3 version source)Setup the command to run the AM listAfter you hit the breakpoint, and then run to the 445 line, you can see that the Vargs looks like this (or see the vargsfinal variable):[%java_home%,-dlog4j.configuration=container-log4j
