http://hadoop.apache.org/releases.html

To verify Hadoop releases using GPG:

  1. Download the release hadoop-X.Y.Z-src.tar.gz from a mirror site.
  2. Download the signature file hadoop-X.Y.Z-src.tar.gz.asc from Apache.
  3. Download the Hadoop KEYS file.
  4. gpg --import KEYS
  5. gpg --verify hadoop-X.Y.Z-src.tar.gz.asc

To perform a quick check using SHA-256:

  1. Download the release hadoop-X.Y.Z-src.tar.gz from a mirror site.
  2. Download the checksum hadoop-X.Y.Z-src.tar.gz.mds from Apache.
  3. shasum -a 256 hadoop-X.Y.Z-src.tar.gz

All previous releases of Hadoop are available from the Apache release archive site.

Many third parties distribute products that include Apache Hadoop and related tools. Some of these are listed on the Distributions wiki page.
