----------------------------------
Hi Experts,
It's really weird that this patch could be applied to trunk in my local env,
but always failed on Apache jira system which
said(https://builds.apache.org/job/Ambari-trunk-test-patch/2758//console):
error: src/main/resources/stacks/HDP/2.2/services/stack_advisor.py: No such
file or directory
PATCH APPLICATION FAILED
However, current patch plans to change file
'ambari-server/src/main/resources/stacks/HDP/2.2/services/stack_advisor.py',
not 'src/main/resources/stacks/HDP/2.2/services/stack_advisor.py', as it
includes following sentences:
--- ambari-server/src/main/resources/stacks/HDP/2.2/services/stack_advisor.py
+++ ambari-server/src/main/resources/stacks/HDP/2.2/services/stack_advisor.py
This patch can be applied to trunk branch in my local env and works well.
Could any expert please help take a review on this issue?
Thanks in advance!

> When we install on a cluster with less than 3 DataNodes, the replication
> factor is set to 3 anyway. It does not make sense. We should change this
> value to a lower number to avoid missing replicas(for example, if there is
> just one DN, set the replication factor to 1).
