Rodolfo Dias updated AMBARI-10354:
----------------------------------
Affects Version/s: 2.2.0
> Ambari agent setup fails on localhost: server creates invalid configuration
> file
> --------------------------------------------------------------------------------
>
> Key: AMBARI-10354
> URL: https://issues.apache.org/jira/browse/AMBARI-10354
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 1.7.0, 2.2.0
> Environment: Centos 6
> Reporter: Nick Ivanov
> Priority: Minor
> Labels: server, setup
> Original Estimate: 10m
> Remaining Estimate: 10m
>
> setupAgent.py attempts to replace the default server setting
> "hostname=localhost" with whatever the user provided. In certain
> circumstances this can make the "hostname" entry invalid. For example: the
> user supplies something that contains "localhost", e.g.
> "localhost.localdomain" and deployment fails for some reason. The user fixes
> the problem and retries deployment, this time the configuration file already
> contains "hostname=localhost.localdomain" and setupAgent.py, when running for
> the 2nd time, turns it into "hostname=localhost.localdomain.localdomain".
> This is a minor issue, obviously, but the use case is still valid when
> installing Ambari on a standalone machine for testing or education.
> The fix would make the regex match more exact, e.g instead of
> {code:title=setupAgent.py}
> osCommand = ["sed", "-i.bak", "s/hostname=localhost/hostname=" +
> server_hostname +
> "/g", "/etc/ambari-agent/conf/ambari-agent.ini"]
> {code}
> use
> {code:title=setupAgent.py}
> osCommand = ["sed", "-i.bak", "s/^hostname=localhost$/hostname=" +
> server_hostname +
> "/", "/etc/ambari-agent/conf/ambari-agent.ini"]
> {code}
