Roman Shaposhnik commented on BIGTOP-566:
-----------------------------------------
Couple of comments:
# we strongly discourage use of upstream scripts in Bigtop, so the invocation
will be /usr/bin/flume-ng --conf-file /etc/flume-ng/conf/flume.conf --conf
/etc/flume-ng/conf --name agent
# my understanding of flume is that it is an agent-based system with long
running agents on each node having a configuration that changes only when the
agent gets restarted. If that's the case then I'd like to propose that the
details of --conf-file get hidden from the end user. on a headless node the
only configuration that flume can rely on would be a static set of configs
under /etc/flume/conf. And that's what should be used by the agent.
Please let me know if this makes sense.
> Flume NG pkg init script should allow user to customize the location of the

> Key: BIGTOP-566
> URL: https://issues.apache.org/jira/browse/BIGTOP-566
> Project: Bigtop
> Issue Type: Bug
> Components: General
> Affects Versions: 0.4.0
> Environment: all
> Reporter: Will McQueen
> Assignee: Bruno Mahé
> Fix For: 0.4.0
>
>
> A typical Flume NG invocation is:
> bin/flume-ng --conf-file conf/flume-conf.properties.template --conf
> conf --name agent1
> ...and the corresponding invocation after installing the Flume NG bigtop
> package would be:
> /usr/lib/flume-ng/bin/flume-ng --conf-file /etc/flume-ng/conf/flume.conf
> --conf /etc/flume-ng/conf --name agent
> The Flume NG init script, installed as part of Bigtop Flume NG, allows us to
> modify:
> 1) the --conf-file value (via FLUME_CONF_FILE)
> 2) the --name value (via FLUME_AGENT_NAME)
> ...but not the --conf value. So the user loses some flexibility when using
> Bigtop Flume NG over Apache Flume NG.
> I recommend that the /etc/init.d/flume-ng-agent script be modified to allow
> the user to set FLUME_CONF_DIR. That is, in this init script, please change
> this:
> FLUME_CONF_DIR=/etc/flume-ng/conf
> ..to this:
> FLUME_CONF_DIR=${FLUME_CONF_DIR:-/etc/flume-ng/conf}
