>          Components: ambari-server
>    Affects Versions: 2.1.0
>            Reporter: Alejandro Fernandez
>            Assignee: Alejandro Fernandez
>             Fix For: 2.1.0

> In Ambari 2.0.0 with HDP 2.2.0.0, HBase has these two properties in hbase-env,
> hbase_master_heapsize
> hbase_regionserver_heapsize
> If a user attempts to add them to hbase-site, then saving the configs will fail.
> Today, the hbase-site validator checks both hbase-site and hbase-env using the recommended
properties for hbase-site. This causes a failure because the properties will exist in the
hbase-site configs, but not in the recommended params for it.
> Further, there's another bug in which the hbase-env properties are not checked at all.
> This was found while changing configs in the HDP sandbox VM.
> PROBLEM: Receiving Error dialog display when trying to add service knox in Sandbox RC
Build "500 status code recieved GET method for API /api/v1/stacks/HDP/versions/2.2/validations"
> This eventually goes through and works, it's just the message is alarming.

> nfs://storage.hwhq.hortonworks.com/corpshare/Robert/SandboxBuilds/ChamplainM10Ambari2.0/Sandbox_HDP_2.2.4_virtualbox_06_04_2015.ova.
> 2.  import sandbox image into virtualbox
> 3.  Start ambari-server and agent since by default sandbox does not start these services
> 4.  Click
> Actions -> + Add service -> select Knox -> next
> you should see some error prompts. you can click next and knox is actually deployed.
