Subject [jira] [Commented] (ACCUMULO-1378) Allow MiniAccumulo cluster configured directory to be used across different runs
Date Tue, 07 May 2013 17:01:17 GMT


Corey J. Nolet commented on ACCUMULO-1378:

bq. are you proposing reorganizing the implementation of MAC or API changes?

I'm referring to reorg of implementations for better code reuse- not API changes. You had
me thinking about having a SingleNodeAccumulo that was different from the MiniAccumuloCluster.
If we did that, many things would remain the same in both- processes get spun up, ports get
configured, LogWriter gets created, shutdown hooks get registered, and vmargs optionally get
attached to the processes for remote debugging. I've been teetering back and forth about this.
On one hand, if the only difference between the two are the ability to re-use a directory/configuration,
that doesn't seem to me like enough of a difference to separate them. On the other hand, if
we want to treat one as a quick integration test environment and the other as a full development
environment then we can define a broader set of features that differentiate the two. The latter
seems like grounds for separation.

> Currently, the MiniAccumuloCluster assumes it should always create the directory structure
and throws an exception if the passed in directory has anything in it.
