where to locate maintenance scripts in ambari cluster machines

[#1]

hi all,

we developed recently couple of shell scripts for cluster maintenance ( as clean logs , collect info , API script etc )

and script must be located in every Linux machine as ( worker machine , data node machine , name node machine )

my question is - were to locate these scripts on each machine? , so it will be safe in case of HDP upgrade or to avoid conflict

for example , we check and we found that each machine have the following empty folder

/var/lib/ambari-agent/lib/

and we are thinking to put all our scripts under /var/lib/ambari-agent/lib

what hortonworks opinion about this , or where is the best location for our scripts that should be located ?

Don't think /var/lib/ambari-agent/lib is good place to keep - As of now it seems Agent upgrade is not removing the files under that path but in future that may/not change - i would recommend to use any custom path outside of ambari-agent

so what are the other places that I can use ?

@Michael Bronson

Ambari agent has below folders

/etc/ambari-agent, /usr/lib/ambari-agent, /usr/sbin/ambari-agent, /var/lib/ambari-agent, /var/lib/ambari-agent/bin/ambari-agent /var/log/ambari-agent, /var/run/ambari-agent

It is better to use some other custom path like /var/lib/ambari-scripts or /var/lib/ambari-custom-scripts

[#5]

in other words you recommended to create new folder on each machine

[#6]

@Michael Bronson yes that is correct.
