Anton Vinogradov commented on IGNITE-4225:
------------------------------------------
Fixed by replacing
{noformat}
AffinityTopologyVersion topVer = cctx.isLocal() ?
cctx.affinity().affinityTopologyVersion() :
cctx.topology().topologyVersion();
{noformat}
with
{noformat}
AffinityTopologyVersion topVer = cctx.isLocal() ?
cctx.affinity().affinityTopologyVersion() :
cctx.shared().exchange().readyAffinityVersion();
{noformat}
To be checked at TeamCity
> DataStreamer can hang on changing topology
