-----------------------------------
Summary: Sudo only when not already root
Key: AMBARI-9391
URL: https://issues.apache.org/jira/browse/AMBARI-9391
Project: Ambari
Issue Type: Improvement
Components: ambari-agent, ambari-server
Affects Versions: 1.7.0
Environment: HDP 2.2
Reporter: Hari Sekhon
When deploying Ambari Agent via Ambari server, avoid use of sudo when already
root as in some environments like mine where root is blocked from making sudo
calls (due to servers being controlled centrally outside my department via
Centrify), it results in failures to deploy agents (which must then be deployed
manually via my own scripting).
It's possible to do something equivalent to this shell paradigm below that I've
used for many years to detect if I'm root/uid 0 and if so just don't prefix
commands with sudo.
{code}[ "$(id -u)" eq "0" ] && sudo="" || sudo=sudo
$sudo command1...
$sudo command2...
{code}
