Maxim Muzafarov commented on IGNITE-7789:
-----------------------------------------
Generally this test fails because of method:
{quote}doTestIgniteOperationOnDisconnect(Ignite client, final List<T2<Callable,
C1<Object, Boolean>>> ops)
{quote}
executes operations in this List<> not in that order in which they are put in.
So, for the first case:
1) Assertion error in test-case:
Here we try to invoke operation here [return dfltCache.invoke(10000, new
CacheEntryProcessor<Object, Object,
Object>()|https://github.com/apache/ignite/blob/master/modules/core/src/test/java/org/apache/ignite/internal/IgniteClientReconnectApiExceptionTest.java#L341]
and expect that key 10_000 already exists in cache (added in previous
opertation in List), but in some cases it not because of execution order.
2) IgniteCheckedException from CacheProcessor on dynamic cache start
Same situation. For method [public void dataStructureOperationsTest() throws
Exception
|https://github.com/apache/ignite/blob/master/modules/core/src/test/java/org/apache/ignite/internal/IgniteClientReconnectApiExceptionTest.java#L97]
we have execution plan:
{quote}OK - test case
[2018-02-27 15:51:05,065][INFO ][async-callable-runner-1][root] Queue creation
[2018-02-27 15:51:05,065][INFO ][async-callable-runner-1][root] Set creation

{quote}
and also number of default backups for [AtomicConfiguration
|https://github.com/apache/ignite/blob/master/modules/core/src/main/java/org/apache/ignite/configuration/AtomicConfiguration.java#L32]
and [CollectionConfiguration
|https://github.com/apache/ignite/blob/master/modules/core/src/main/java/org/apache/ignite/configuration/CollectionConfiguration.java#L47]
are different:
{quote}CollectionConfiguration we have default backup = 0;
AtomicConfiguration we have DFLT_BACKUPS = 1;
{quote}
I suggest to rewrite hole test in the correct way, but I think this is for
another task.
