Pavel Tupitsyn updated IGNITE-21765:
------------------------------------
    Description: 
* *ClientTable.getPartitionAssignment* might return an empty list
* *AbstractClientStreamerPartitionAwarenessProvider* assumes that partition 
count can't change

Therefore, if some server node lags behind and returns an empty assignment for 
a given timestamp, streamer partition awareness won't work at all.

> Java thin 3.0: DataStreamer partition awareness might break if assignment is 
> not available at the moment
