Subject [jira] [Commented] (ACCUMULO-2739) Create an In-Process MiniAccumuloCluster
Date Fri, 30 May 2014 19:37:02 GMT


Josh Elser commented on ACCUMULO-2739:

Well, "slowness" is only half of the concerns. I'd agree with you that there are probably
other things we could change to just make MAC faster.

The other big reason for doing this is the ease in stepping through Accumulo. It would be
nice in debugging some code in Accumulo to just launch a test case and use the single debugger
instance that covers both the client and Accumulo code. This also seems to be a common thing
(at least those with Cassandra experience frequently ask for this from Accumulo).

> Two common griefs about MiniAccumuloCluster is that it's slow to start and it is difficult
to debug things running inside of the Master or TabletServer (because they are in separate
> Running each Accumulo process inside of the parent process would likely increase startup
speed and would make debugging much easier (as you wouldn't have to remote-attach the debugger
> Such a MAC would likely also pave the way for easier migration away from MockAccumulo
as both of the above complaints are some of the primary concerns for removing Mock with no
