ambari-server/src/main/resources/stacks/HDP/2.0.6/services/stack_advisor.py <https://reviews.apache.org/r/31891/#comment123210> 1. The warning looks very dangerous, lets tone it down to: It is recommended to host Ambari Metrics with to ensure there is enough RAM avaialble for embedded HBase. 2. We should throw this warning after checking memory so if ther is 64 GB avaialble memory and there is 1 or 2 masters, we can ignore the warning. How about for now lets say more than 2 masters and if memory is less that 32 GB, throw warning? - Sid Wagle On March 10, 2015, 3:39 p.m., Dmytro Sen wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
