Compiling Dependencies

  1. Use the Yum source to install the base library.
    1
    yum install openssl-devel zlib-devel automake libtool
  2. Optional: Compile Snappy.

    Snappy is an optional compression library. You can add compilation options to the Hadoop software package.

    1. Download the Snappy dependency package.
      1
      wget https://github.com/google/snappy/archive/refs/tags/1.1.7.tar.gz

      The name of the installation package downloaded using the wget command is 1.1.7.tar.gz, while that downloaded using the browser is snappy-1.1.7.tar.gz.

    2. After decompression, go to the target directory. For example, if the downloaded installation package is named 1.1.7.tar.gz, run the following commands:
      1
2
      tar -zxvf 1.1.7.tar.gz
cd snappy-1.1.7
    3. Modify the CMakeLists.txt file to enable the dynamic link library compilation.
      1. Open the file.
