Cloudera Enterprise 5.1 is Now Available

Cloudera Enterprise’s newest release contains important new security and performance features, and offers support for the latest innovations in the open source platform.

We’re pleased to announce the release of Cloudera Enterprise 5.1 (comprising CDH 5.1, Cloudera Manager 5.1, and Cloudera Navigator 2.0).

Cloudera Enterprise 5, released April 2014, was a milestone for users in terms of security, performance, and support for the latest community-driven innovations, and this update includes significant new investments in those areas, as well as a host of bug fixes. Here are some of the highlights (incomplete; see the Release Notes for CDH, Cloudera Manager, and Cloudera Navigator for a full list of features and fixes):

    Unlike previous versions, CM 5.1.3 is tightly coupled to OS version. It fails on start, on RedHat/CentOS v7 with this error:
    Your distribution is not supported. This installer supports:
    * RedHat Enterprise Linux 5 or 6
