Subject [jira] [Commented] (ACCUMULO-1785) Alter config.sh to optionally just verify environment instead of making changes
Date Wed, 04 Dec 2013 20:08:36 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13839293#comment-13839293
] 

Keith Turner commented on ACCUMULO-1785:
----------------------------------------

[~busbey] I applied the patch.  There were merge conflicts when applying to 1.4.5-SNAPSHOT
which I resolved.  When I merged it into 1.5.1-SNAPSHOT there were also merge conflicts which
I resolved.  It merged cleanly from 1.5 to 1.6.  Can you check the 1.4 and 1.5 conflict resolution?

> 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.
