> Requirements:
> - ambari should drop JDK 7 support for ambari-server and ambari-managed services (infra,
ams, logsearch)
> - HDP 2.x should be still able to use JDK 1.7
> Changes in ambari setup:
> 1. First the usual ambari setup
> {code:java}
> Choose JDK for Ambari and Stack services:
> [1] Oracle JDK 1.8 + Java Cryptography Extension (JCE) Policy Files 8
> [2] Oracle JDK 1.7 + Java Cryptography Extension (JCE) Policy Files 7
> [3] Custom JDK
> {code}
> 2. If JDK 7 is picked, that cannot be used for ambari (only for the stack services)
> {code:java}
> JDK 7 is detected (JDK 8 required for ambari-server), install JDK 8 as well:
> [1] Oracle JDK 1.8 + Java Cryptography Extension (JCE) Policy Files 8
> [3] Custom JDK
> {code}
> After the commands are executed, the following properties would appear in ambari.properties
> {code:java}
> stack.java.home=/usr/jdk64/jdk1.7.0_67
> stack.jdk.name=jdk-7u67linux-x64.tar.gz
> stack.jce.name=UnlimitedJCEPolicyJDK7.zip
> {code}
> During command.json generating, commandParameters would be filled with proper ambari
jdk,jce info (different for infra/logsearch/ams from other services) - not hostLevelParams,
as multiple command could use the same hostLevelParams (like start all services: that can
start zookeeper and ams as well with the same hostLevelParams)
> On ambari-upgrade, ambari process wont be able to start with jdk7 so it will be required
to run ambari-server setup first (you can skip the first change jdk part, but then the user
will see its needed to setup a different jdk for ambari)
> In the future, it will be recommended to do the JDK upgrade before upgrading to HDP 3.0
(to avoid some issues during HDP upgrade)
