Sergey Chugunov commented on IGNITE-7330:
-----------------------------------------
[~mmuzaf],
This issue is very old, is it still reproducible at all? If it's not all we
need to do is just to close the issue.
Anyway I've never seen about problems like this on user list so moving it to
the next release is also OK I think.

> Key: IGNITE-7330
> URL: https://issues.apache.org/jira/browse/IGNITE-7330
> Project: Ignite
> Issue Type: Bug
> Reporter: Sergey Chugunov
> Priority: Critical
> Labels: IEP-4, Phase-2
> Fix For: 2.8
>
>
> The test below reproduces the issue:
> {noformat}
> public void testClientJoinWhenActivationInProgress() throws Exception {
> Ignite srv = startGrids(5);
> srv.active(true);
> srv.createCaches(Arrays.asList(cacheConfigurations1()));
> Map<Integer, Integer> cacheData = new LinkedHashMap<>();
> for (int i = 1; i <= 100; i++) {
> for (CacheConfiguration ccfg : cacheConfigurations1()) {
> srv.cache(ccfg.getName()).put(-i, i);
> cacheData.put(-i, i);
> }
> }
> stopAllGrids();
> srv = startGrids(5);
> final CountDownLatch clientStartLatch = new CountDownLatch(1);
> IgniteInternalFuture clStartFut = GridTestUtils.runAsync(new
> Runnable() {
> @Override public void run() {
> try {
> clientStartLatch.await();
> Thread.sleep(10);
> client = true;
> Ignite cl = startGrid("client0");
> IgniteCache<Object, Object> atomicCache =
> cl.cache(CACHE_NAME_PREFIX + '0');
> IgniteCache<Object, Object> txCache =
> cl.cache(CACHE_NAME_PREFIX + '1');
> assertEquals(100, atomicCache.size());
> assertEquals(100, txCache.size());
> }
> catch (Exception e) {
> log.error("Error occurred", e);
> }
> }
> }, "client-starter-thread");
> clientStartLatch.countDown();
> srv.active(true);
> clStartFut.get();
> }
> {noformat}
> Expected behavior: test finishes successfully.
> Actual behavior: test hangs on waiting for client start future to complete
> while "client-started-thread" will be hanging on obtaining a reference to the
> first cache.
