--------------------------------------------
Summary: Stack Validator fails when when HBase properties
hbase_master_heapsize or hbase_regionserver_heapsize are added to both
hbase-env and hbase-site - returns 500 error
Key: AMBARI-10451
URL: https://issues.apache.org/jira/browse/AMBARI-10451
Project: Ambari
Issue Type: Bug
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.

BUSIMPACT: Can potentially cause confusion for the customer.
STEPS TO REPRODUCE:
1. Download RC build of Sandbox :
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.
