[jira] [Created] (IGNITE-11238) Possible hang on exchange

Igor Seliverstov created IGNITE-11238:
-----------------------------------------

             Summary: Possible hang on exchange
                 Key: IGNITE-11238
                 URL: https://issues.apache.org/jira/browse/IGNITE-11238
             Project: Ignite
          Issue Type: Bug
          Components: general
            Reporter: Igor Seliverstov


Currently we may hang on exchange for a while (two network timeouts) waiting for release a latch (see {{GridDhtPartitionsExchangeFuture#waitPartitionRelease releaseLatch}}) in case a processing topology version has not been added to discovery history yet but client acknowledge already received by coordinator:

{code:java}
[2019-02-06 17:43:17,009][ERROR][sys-#43%mvcc.CacheMvccPartitionedSqlCoordinatorFailoverTest0%][ExchangeLatchManager] Topology AffinityTopologyVersion [topVer=24, minorTopVer=0] not found in discovery history ; consider increasing IGNITE_DISCOVERY_HISTORY_SIZE property. Current value is -1
class org.apache.ignite.IgniteException: Topology AffinityTopologyVersion [topVer=24, minorTopVer=0] not found in discovery history ; consider increasing IGNITE_DISCOVERY_HISTORY_SIZE property. Current value is -1

{code}

This way the received ack won't be processed, so, we will be waiting for retry:
{code:java}
                    // Try to resend ack.
                    releaseLatch.countDown();
{code}

To solve the issue we need to test whether the version is present in discovery history and put it into a pending map if i isn't so (see {{ExchangeLatchManager#pendingAcks}})
