Hi,   [33m[2020.09.08 21:19:28.898] [WARN ] [o.a.i.i.p.r.h.t.GridTaskCommandHandler] Failed to execute task due to topology issues (are all mapped nodes alive?) [name=o.a.i.i.v.compute.VisorGatewayTask, clientId=null, err=class o.a.i.IgniteCheckedException: Failed to reduce job results due to undeclared user exception [task=o.a.i.i.v.compute.VisorGatewayTask@6eb42aa, err=class o.a.i.cluster.ClusterGroupEmptyException: Topology projection is empty.]]     Well, it’s the VisorNodeConfigurationCollectorTask that’s trying to execute, but failed cause the server is not ready. Do you use the Visor for cluster monitoring? I think it’s fine to ignore it, but it’s worth understanding what’s launching it.   From: kay Sent: Wednesday, September 9, 2020 2:48 AM To: user@ignite.apache.org Subject: Re: ClusterGroupEmptyException: Topology projection is empty.   Hello   Here is my full log NexusCache1-1-1.out <http://apache-ignite-users.70518.x6.nabble.com/file/t2778/NexusCache1-1-1.out>    I'm using 2.8.0 version and I don't use any clustergroup configuration.   Thank you!       -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
