> For now, partition store BTree can be destroyed while vacuum in progress regardless partition reservations which causes VacuumTask failure without negative side effect (such as worker failure or any hanging).
>  VacuumTask successfully catch and log the exception, but further check in afterTest() method reports vacuum failure.
>  For now vacuum is disabled for this test.
> We should fix vacuum failure properly in that case and fix CacheMvccPartitionedSqlQueriesTest.testDistributedJoinSimple() test.
