The problem after the ignite upgrade

[hulitao198758 <hu...@lenovo.com>]

The problem with the Ignite version upgrading from 2.3 to 2.6 is that when
the Server side starts up, the client will report an error when connecting
to the Server side. The client must first stop activating the Server side,
then connect with the client once, and then reactivate the Server side
before the client can connect properly. Why? Is this a BUG

Hi,

Clients should be able to connect to the cluster normally.
Please share logs if you’re still seeing this.

I opened the persistent storage cluster, version 2.3 as long as the boot
server and then activate the cluster when the client can be connected
directly, after upgrading to 2.6, after activation server cluster for the
first time the client connection complains, you then need to Deactive the
cluster with clients to connect again later, in an error once, then again to
reactivate can connect successful, why?

Hi,

Could you please provide step by step instruction on how you upgrade the
cluster?

Please note that in case if you try to use the persistence then the
important feature that was added in 8.4 - baseline topology. A baseline
topology is a set of Ignite server nodes intended to store data. The nodes
from the baseline topology are not limited in terms of functionality and
behave as regular server nodes that act as a container for data and
computations in Ignite.

It changes the activation process. You can read about it here:

https://apacheignite.readme.io/docs/baseline-topology

BR,
Andrei
