Andrey Mashenkov updated IGNITE-18328:
--------------------------------------
Description:
Scenario
* Start gird [CGM, MetaStorage, DataNode]
* Stop MetaStorage node
* Run "Create table" sql query.
* Future returns cursor, but the cursor can't retrieve data from it.
* Observing in thread dump: Reading next batch (requestNextAsync) future can't
be failed as ForkJoinPool thread blocked with bulk of tasks:
{code:java}
at j.u.c.CompletableFuture.get(CompletableFuture.java:1998)
at o.a.i.i.m.client.CursorImpl.close(CursorImpl.java:90)
at
o.a.i.i.m.client.MetaStorageServiceImpl$WatchProcessor.lambda$stopWatch$1(MetaStorageServiceImpl.java:580)
{code}
See reproducer in IGNITE-18171 PR in ignite-runner module:
