Review request for Ambari, Dmitro Lisnichenko, Gautam Borad, Myroslav Papirkovskyy, Srimanth
Gunturi, and Sid Wagle.

Bugs: AMBARI-10451

Repository: ambari


In Ambari 2.0.0 with HDP, HBase has these two properties in hbase-env,
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.

Testing (updated)

Reproduced the issue on a live cluster and verified that the following works.
 A. hbase-env hbase_master_heapsize set to 512 fails
 B. hbase-env hbase_master_heapsize set to 1024 passes
 C. Scenario B + hbase-site hbase_master_heapsize set 512 passes since that property is not
 D. Introduced an error in the on purpose to test the error message in
the dialog box

Unit tests passed,
