Looks like it is the same test as in master [https://ci.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=-1194594567102543889&tab=testDetails]. Now name generated by parameters.

> Page replacement can reload invalid page during checkpoint
> There is a race between {{writeCheckpointPages}} and page replacement process:
> * Checkpointer thread begins a checkpoint
> * Checkpointer thread calls {{getPageForCheckpoint()}}, which will copy page content *and clear dirty flag*
> * Page replacement tries to find a page for replacement and chooses this page, the page is thrown away
> * Before the page is written back to the store, the page is acquired again.
> As a result, an older copy of the page is brought back to memory, which causes all kinds of corruption exceptions and assertions.
> ----
> checkpointReadLock() may hang during node stop
> I got this hang during one of PDS (Indexing) runs (thread-dump is attached).
> The following code hang:
> {code:java}
> checkpointer.wakeupForCheckpoint(0, "too many dirty pages").cpBeginFut
> .getUninterruptibly();
> {code}
> It looks like {{wakeupForCheckpoint}} can be called after the checkpointer is stopped and {{cpBeginFut}} will be never completed.
> ----
> Fixed ZookeeperDiscoveryCommunicationFailureTest.testCommunicationFailureResolve_CachesInfo1
> Fixed *.testFailAfterStart
> Reduce test time execution (scale factor for a long-running tests)
