---------------------------------------
Summary: Zookeeper test case
testCommunicationFailureResolve_KillRandom frequently fails in
GridAbstractTest.waitForTopology
Key: IGNITE-10988
URL: https://issues.apache.org/jira/browse/IGNITE-10988
Project: Ignite
Issue Type: Bug
Affects Versions: 2.7
Reporter: Oleg Ignatenko
Zookeeper test case testCommunicationFailureResolve_KillRandom frequently fails
in GridAbstractTest.waitForTopology.
Teamcity test history in master currently shows "Test runs: 625 total / 251
failures"
([link|https://ci.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=-3849782382784091413&tab=testDetails).
Need to find out why is that and whether test case can be improved and made
more reliable.
Typical failure message looks as follows:
{noformat}
[2019-01-18 06:57:23,489][ERROR][main][root] Test failed.

----
Side note per IGNITE-10777 this test case has moved to another class, from
{{ZookeeperDiscoverySpiTest}} to {{ZookeeperDiscoverySpiTest5}} but that didn't
change anything: it still fails frequently and failure message is the same,
with the only difference in the new test class name.
