John Vines commented on ACCUMULO-244:
-------------------------------------

Yes, network partitioning is still a concern that we are not testing thoroughly against.

> We currently test faults at scale by killing server processes while running a test suite
like continuous ingest or random walk.  We need to test partitions at scale. We need to take
subsets of processes and partition them from all other processes while running a test suite.
 
> What is the easiest way to simulate this?  The only option I can think of at the moment
is 'ifdown eth0; sleep xxx; ifup eth0'.  I do not like this option though.  Would rather do
something at the process level though instead of the server level.
