(Updated Jan. 26, 2016, 11:12 p.m.)


Review request for Ambari, Dmytro Sen, Sumit Mohanty, and Sid Wagle.


Changes
-------

Actual was that hbase_regionserver_heapsize was not used for calculating memory required on
host.


Bugs: AMBARI-14769
    https://issues.apache.org/jira/browse/AMBARI-14769


Repository: ambari


Description
-------

PROBLEM
Stack advisor recommendations for AMS heap sizes are unreasonable.

BUG
Stack advisor uses fixed values of 1024M for metrics collector and HBase heapsize for estimating
required memory for the components in the host.

FIX
Use the user entered values for metrics collector heapsize and AMS HBase heapsize to calculate
the required memory on the host.


Diffs (updated)
-----

  ambari-server/src/main/resources/stacks/HDP/2.0.6/services/stack_advisor.py 5bcebf7 

Diff: https://reviews.apache.org/r/42640/diff/


Testing
-------

ambari-server python unit tests pass.

Manual testing done.


Thanks,

Aravindan Vijayan
