Thanks Dmitro!

So one entry in “general_deps” like:

"HIVE_SERVER-START": ["NODEMANAGER-START", "MYSQL_SERVER-START"]


Means before “start HIVE_SERVER” ,  "NODEMANAGER-START" and 
"MYSQL_SERVER-START" should be executed first?   And :



"NAGIOS_SERVER-INSTALL" : ["HIVE_CLIENT-INSTALL", "HCAT-INSTALL", 
 "MAPREDUCE_CLIENT-INSTALL", "OOZIE_CLIENT-INSTALL"],



Means before “NAGIOS_SERVER-INSTALL", several components like 
“HIVE_CLIENT”, “HCAT”, “MAPREDUCE_CLIENT” and “OOZIE_CLIENT” should be 
installed first ?

Hi


As I remember, key is just an action (e.g. start component 
HIVE_SERVER), and value is just a list "what should be executed 
before". role_command_order.json complements dependencies inherited 
from parent stack, if any.


Hope this helps

    Hi,

    I am new to Ambari and trying to create my own non-HDP stack.
    Could anyone please tell me any detailed specification info about
    the file role_command_order.json, like how to define the key-value
    pair in this file?

    Thanks,

    -Tao
