Andrew Mashenkov updated IGNITE-4424:
-------------------------------------
Description:
Replicated cache sometimes won't sync across nodes properly.
PFA a reproducer code.
All nodes are started at the same time on different machines:
* Ignition.start() // Blocks until node is up
* Only one of the nodes performs next: getOrCreateCache() then putAll()
* All the other nodes block on this before proceeding.
* All of the nodes perform next:
** getOrCreateCache() // Again
** cache.localSize(CachePeekMode.ALL)
All nodes should see filled cache, but sometimes some nodes see empty cache.
LocalSize call can be replaced by iterating over cache, but result will be same.
Logs says that more than one cluster is started unexpectedly, but there is no
errors at all.
I'd run test in infinite loop and it failed in two hours. It looks like there
is a race. Possibly, it is harder to reproduce on single machine due to small
latency.
