Cloudera，Oracle JDK和Open JDK

Question

必须使用Oracle JDK而不是Open JDK来安装cloudera的库，以使cloudera集群在redhat机器上吗？

Answer 1

At the time of writing, only Oracle JDK releases are certified for use with Cloudera products; see

• Cloudera Enterprise 6 Release Guide > Requirements and Supported Versions > Java Requirements

In the future this may change. According to a Cloudera employee reply to a Cloudera Community posting.

There is currently work-in-progress thing to certify some of the OpenJDK versions against Cloudera suite of products. We can expect the official announcement once the testing and certification are complete for the future CM/CDH releases.

Of course, even now you could ignore this requirement and use an OpenJDK Java or some other non-Oracle Java. But if you encountered problems, Cloudera Support may not be able to help you.
