[infinispan-dev] NBST test failures in Query

[Sanne Grinovero]

I'm having a couple of tests in the Query module sporadically (but
often) failing because of exceptions like:

 - Received invalid rebalance confirmation from NodeC-62354 for cache
___defaultcache, we don't have a rebalance in progress
 - Suspected members
 - WARN  [InboundTransferTask] (transport-thread-1,NodeD) ISPN000210:
Failed to request segments [0, 2, 4, 36, 6, 42, 8, 43, 40, 10, 41, 11,
12, 13, 14, 50, ...
 - ISPN000071: Caught exception when handling command
CacheTopologyControlCommand ...

Looks very much state-transfer related to me. Could anyone from the
NBST experts have a look?

There are some interesting test there:
org.infinispan.query.distributed.MultiNodeDistributedTest

and its extensions explicitly attempt to start additional nodes,
scaling up and down while performing other operations. To be fair, I
wish they would really do thinks in parallel, but they are politely
blocking and waiting for rehashing to complete at each step..

I would expect at this point to see some tests doing operations and -
in parallel - have nodes added and removed. Are there no such tests in
core?
