             Summary: [Test failure] GridCacheClientModesTcpClientDiscoveryAbstractTest$CaseNearReplicatedTransactional.testGetFromClientNode
                 Key: IGNITE-6234
                 URL: https://issues.apache.org/jira/browse/IGNITE-6234
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.1
            Reporter: Sergey Chugunov
            Assignee: Sergey Chugunov
             Fix For: 2.2


Test reproducible locally although with a very low probability. 
I wasn't able to reproduce it starting test in isolation but managed to do it starting *GridCacheClientModesTcpClientDiscoveryAbstractTest* 50 times in a row observing from 1 to 3 failures.

It seems that when client requests value of custom class from near cache it may see BinaryMetadata for this class with no schema.

Test fails with the following exception:
{noformat}

Quick fix: add null check for schemaIds.
