Subject [jira] [Commented] (ACCUMULO-1785) Alter config.sh to optionally just verify environment instead of making changes
Date Mon, 09 Dec 2013 23:05:07 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13843665#comment-13843665
] 

Josh Elser commented on ACCUMULO-1785:
--------------------------------------

bq. That was an intentional change. Can we file a follow on ticket for the verification of
a set ACCUMULO_HOME?

Ok, I wasn't sure because things suddenly broke for me after this change, despite not setting
ACCUMULO_VERIFY_ONLY. Opened ACCUMULO-1997.

> 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.
