Sean Busbey updated ACCUMULO-1785:
----------------------------------
Attachment: ACCUMULO-1785.1.patch.txt
Patch against 1.4.5-SNAPSHOT for changes to implement ACCUMULO_VERIFY_ONLY for
bin/config.sh.
Can't get review board to work against the Accumulo project ATM. So I'll just
put everything here.
Testing done:
* functional tests
* starting w/o env variable set and no master/slaves correctly started in
standalone mode.
* starting w/env variable and no required variables and no master/slaves
correctly complained and failed.
* starting w/env variable and required variables and no master/slaves correctly
init w/o writing crap, correctly failed to use start-all
* starting with a normal cluster config
One bit I'm not sure about: ${GC} and ${MONITOR}. Right now they're inferred if
not present. If we're in VERIFY_ONLY mode, I'm not sure they're actually
needed. AFAICT, they're only used in the bin/{start|stop}-* scripts.
Any thoughts about pulling the entire checking/setting of them into the
non-verify-only mode?

>
> Right now, the accumulo scripts presume that invocation always happens on a
> node in the cluster. This makes integrating with external cluster management
> software more difficult.
> The primary issue is that bin/config.sh expects to find a full cluster
> configuration directory at all times. In the case of a configuration
> directory that doesn't specify any hosts it takes steps to set up a
> standalone cluster. That effort is unneeded and undesirable if we're just
> e.g. trying to go through init from a non-participant host.
> Add an optional environment variable to have config.sh just verify the
> invariants needed for bin/accumulo to behave correctly. When present, don't
> make local directories or write to files.
