[jira] [Commented] (IGNITE-8098) Getting affinity for topology
version earlier than affinity is calculated because of data race

> From time to time the Ignite cluster with services throws next exception during restarting of some nodes:
> java.lang.IllegalStateException: Getting affinity for topology version earlier than affinity is calculated [locNode=TcpDiscoveryNode [id=c770dbcf-2908-442d-8aa0-bf26a2aecfef, addrs=[10.44.162.169, 127.0.0.1], sockAddrs=[clrv0000041279.ic.ing.net/10.44.162.169:56500, /127.0.0.1:56500], discPort=56500, order=11, intOrder=8, lastExchangeTime=1520931375337, loc=true, ver=2.3.3#20180213-sha1:f446df34, isClient=false], grp=ignite-sys-cache, topVer=AffinityTopologyVersion [topVer=13, minorTopVer=0], head=AffinityTopologyVersion [topVer=15, minorTopVer=0], history=[AffinityTopologyVersion [topVer=11, minorTopVer=0], AffinityTopologyVersion [topVer=11, minorTopVer=1], AffinityTopologyVersion [topVer=12, minorTopVer=0], AffinityTopologyVersion [topVer=15, minorTopVer=0]]]
> Looks like the reason of this issue is the data race in GridServiceProcessor class.
> How to reproduce:
> 1)To simulate data race you should update next place in source code:
> Class: GridServiceProcessor
> Method: @Override public void onEvent(final DiscoveryEvent evt, final DiscoCache discoCache) {
> Place:
> ....
> try {
> svcName.set(dep.configuration().getName());
> ctx.cache().internalCache(UTILITY_CACHE_NAME).context().affinity().
> affinityReadyFuture(topVer).get();
> //HERE (between GET and REASSIGN) you should add Thread.sleep(100) for example.
> //try {
> //Thread.sleep(100);
> //}
> //catch (InterruptedException e1) {
> //e1.printStackTrace();
> //}
>
> reassign(dep, topVer);
> }
> catch (IgniteCheckedException ex) {
> if (!(e instanceof ClusterTopologyCheckedException))
> LT.error(log, ex, "Failed to do service reassignment (will retry): " +
> dep.configuration().getName());
> retries.add(dep);
> }
> ...
> 2)After that you should imitate start/shutdown iterations. For reproducing I used GridServiceProcessorBatchDeploySelfTest (but timeout on future.get should be increased to avoid timeout error)
