Snappy Installation

Snappy is a compression/decompression library. It optimizes for very high-speed compression and decompression, and moderate compression instead of maximum compression or compatibility with other compression libraries.

    Installing Snappy

    Snappy is provided in the hadoop package along with the other native libraries (such as native gzip compression).

      Warning: If you install Hadoop from a tarball, Snappy may not work, because the Snappy native library may not be compatible with the version of Linux on your system. If you want to use Snappy, install CDH 5 from the RHEL or Debian packages.

    To take advantage of Snappy compression you need to set certain configuration properties, which are explained in the following sections.

    Upgrading Snappy

    To upgrade Snappy, simply install the hadoop package if you haven't already done so. This applies whether you are upgrading from CDH 4 or from an earlier CDH 5 release.

      Note: To see which version of Hadoop is shipping in CDH 5, check the Version and Packaging Information. For important information on new and changed components, see the CDH 5 Release Notes.
