You can use `git grep "/usr/hdp"` to search, i am sure that many
scripts do not belong only to the HDP stack:

$ git grep "/usr/hdp" | cut -d ':' -f1 | sort -u

The only scripts which should use /usr/hdp as a hard coded value are those 
which belong specifically to the HDP stack. Otherwise it's a bug and needs to 
be corrected.

But i find some python script use "/usr/hdp" as hard code, is there a plan to
make it synchronize with stack_root val?

It doesn't create that directory, as ambari does not know what could be
used. The service RPMs create directories upon installation and Ambari
reads its content. That's about it.

why stack_root does not exist

[xiang . dai]

HI! 

I define a new stack called DX and change the stack_root to {DX: /usr/dx} in 
the cluster_env.xml, the old is {HDP: /usr/hdp}. 

But when i start install, i find below error: 

WARNING 2018-03-22 10:05:49,709 base_alert.py:138 - 
[Alert][ambari_agent_disk_usage] Unable to execute alert. [Errno 2] No such 
file or directory: '/usr/dx' 

Does it mean ambari can not auto mkdir this one? 

If i miss something important, please tell me. 

Best Wishes
