Hadoop HDP JDK vs JRE Installation and Requirements

Hadoop HDP JDK vs JRE Installation and Requirements

Explorer

Is it still mandatory only to use JDK and not JRE while setting up an HDP cluster?

One of the Production Clusters being setup using localrepository ( no internet access) is showing errors during installation.

While referring https://docs.hortonworks.com/HDPDocuments/Ambari-2.7.3.0/ I see all references to JDK and not JRE

Can this be an issue?
