---------------------------------------
Summary: Add API for checking network connectivity between all
nodes in a cluster
Key: IGNITE-13766
URL: https://issues.apache.org/jira/browse/IGNITE-13766
Project: Ignite
Issue Type: Task
Components: control.sh
Affects Versions: 2.9
Reporter: Semyon Danilov
Assignee: Semyon Danilov
Fix For: 2.9.1
Lack of connectivity from Server to client nodes could be a huge problem for
cluster stability. The client will be able to connect to the server and the
server will be able to answer to the client as long as the connection
established by the client will live, but if it will be closed and the server
will try to establish it's own connection, it will just hang(along with an
operation, which requires a message to be sent to the client node, it could be
topology change or some snapshot stage change, etc).
We should introduce an API, which will be available from control.sh and will
allow checking the connectivity between all nodes in the cluster. NOTE that
nodes should always try to establish it's own connection instead of just
reusing the connection that was established by another node.
