-------------------------------------
Summary: Alter config.sh to optionally just verify environment
instead of making changes
Key: ACCUMULO-1785
URL: https://issues.apache.org/jira/browse/ACCUMULO-1785
Project: Accumulo
Issue Type: Improvement
Components: scripts
Affects Versions: 1.5.0, 1.4.4
Reporter: Sean Busbey
Priority: Minor
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.
