Support Notes

Only 64 bit JDKs are supported.

Unless specifically excluded, Cloudera supports later updates to a major JDK release from the release that support was introduced. Cloudera excludes or removes support for select Java updates when security is jeopardized.

Running Runtime nodes within the same cluster on different JDK releases is not supported. All cluster hosts must use the same JDK update level.
