Prachi, thanks!
Documentation looks good now.

Exactly. Persistent cluster can't exist in active state
without baseline topology. First activation will establish BLT
from current set of server nodes.

Hi Ivan,
I have fixed and rephrased the section -
https://apacheignite.readme.io/v2.5/docs/baseline-topology#section-cluster-activation
<https://apacheignite.readme.io/v2.5/docs/baseline-topology#section-cluster-activation>
However, I have a question regarding setting the baseline
topology when activating the cluster for the first time. In
the web console, when we activate the cluster, using the
toggle switch, all server nodes in the cluster are
automatically added to the baseline topology. Does this mean
that when we activate the cluster for the first time, via
code, we do not need the following piece code?
// Get all server nodes that are already up and running.
Collection<ClusterNode> nodes =
ignite.cluster().forServers().nodes();
// Set the baseline topology that is represented by these nodes.
ignite.cluster().setBaselineTopology(nodes);
I guess just activating the cluster would add all the
existing nodes to the baseline topology?

I've tried to execute exactly the same code, it resulted with
class org.apache.ignite.IgniteException: Changing
BaselineTopology on inactive cluster is not allowed.
Basically, the code snippet is in "Setting the Topology
From Code" section, so we can make it correct by just
removing "activation" and "first baseline topology" parts.

Prachi,
I do remember that that code, Ivan is referring to,
worked fine for you.
Please double check. Probably you need to add
"ignite.cluster.activate()"
to the code snippet.

Igniters,
Seems like we have an inconsistency in our
Baseline Topology
documentation:
https://apacheignite.readme.io/docs/baseline-topology#section-setting-the-topology-from-code
<https://apacheignite.readme.io/docs/baseline-topology#section-setting-the-topology-from-code>
Java developers can use the IgniteCluster
interface to initialize the
very first baseline topology or to adjust an
existing one. The sample
below shows how to add all the existing
server nodes to the baseline
topology:
// Connecting to the cluster.
Ignite ignite = Ignition.start();
// Setting the baseline topology to a
specific Ignite cluster topology
version.
ignite.cluster().setBaselineTopology(2);
This is not true; baseline topology can't be
changed on inactive
cluster. The only viable way to initialize the
very first baseline
topology is manual cluster activation. This is
correctly explained in
this section:
https://apacheignite.readme.io/docs/baseline-topology#section-first-cluster-startup
<https://apacheignite.readme.io/docs/baseline-topology#section-first-cluster-startup>
