(Configuring Hadoop on Windows requires some preparation, including software downloads, understanding the conditions under which Hadoop runs, and understanding the differences between Hadoop on Linux and Windows platforms. The basic tools required for Hadoop installation are Hadoop installation package, jdk development tools, and Cygwin installer. Among them, the jdk version is preferably above 1.6. Considering the compatibility and functional integrity, we choose the Hadoop-0.20.2 version; because we are simulating the Linux platform to configure Hadoop, we need to install Cygwin on the computer first, and provide other software. Shell support, you can choose to install from the Cygwin installation package directory you downloaded during installation, or you can choose to install directly from the Internet. It may take longer to install from the Internet, and we will introduce it in detail below.)
