Subject [jira] [Commented] (ACCUMULO-1785) Alter to optionally just verify environment instead of making changes
Date Thu, 05 Dec 2013 18:18:35 GMT


Sean Busbey commented on ACCUMULO-1785:

The merges to 1.4.5-SNAPSHOT and 1.5.1-SNAPSHOT look fine, though as mentioned in ACCUMULO-1901
the behavior of GC stuff changed. I'll put a note there about it.

> 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/ 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 just verify the invariants needed
for bin/accumulo to behave correctly. When present, don't make local directories or write
to files.
