Download CDH 5.4.4
Get the most out of your data with CDH
The world's most popular Hadoop platform, CDH is Cloudera's 100% open source platform that includes the Hadoop ecosystem.
Built entirely on open standards, CDH features all the leading components to store, process, discover, model, and serve unlimited data.
Long term component architecture
As the main curator of open standards in Hadoop, Cloudera has a track record of bringing new open source solutions into its platform (such as Apache Spark, Apache HBase, and Apache Parquet) that are eventually adopted by the community at large. As standards, you can build longterm architecture on these components with confidence.
PLEASE NOTE:
With the exception of DSSD support, Cloudera Enterprise 5.6.0 is identical to CDH 5.5.2/Cloudera Manager 5.5.3 If you do not need DSSD support, you do not need to upgrade if you are already using the latest 5.5.x release.

Hue with SSL Fails to Start in CDH 5.4.3
In CDH 5.4.3, Hue with SSL fails to start because a pyOpenSSL package is missing in the parcel. This applies to both new installs and upgrades and is not operating-system specific.
Bug: None
Severity: High
Release affected: CDH 5.4.3
Release containing the fix: CDH 5.4.4
Workaround:
- Download the package:
- cd /tmp
- curl -O https://pypi.python.org/packages/source/p/pyOpenSSL/pyOpenSSL-0.13.tar.gz
- Determine the Hue installation directory:
- Parcels:
export HUE_DIR=/opt/cloudera/parcels/CDH-5.4.3-1.cdh5.4.3.p0.6/lib/hue
- Packages:
export HUE_DIR=/usr/lib/hue
- Parcels:
- Change to the Hue installation directory:
cd $HUE_DIR
- Do the following, depending on your OS:
- On CentOS/RedHat 6.x:
- sudo yum install gcc python-devel openssl-devel
- sudo ./build/env/bin/python ./build/env/bin/pip -v install /tmp/pyOpenSSL-0.13.tar.gz
- On Ubuntu 14.04:
- sudo apt-get install gcc python-dev python-pip libssl-dev
- sudo pip install --target=`pwd`/`ls -d build/env/lib/python*/site-packages` /tmp/pyOpenSSL-0.13.tar.gz
- On other platforms, contact Support for assistance.
