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.
