Hi Nithin,
You face current message because your client lost the connection to the
server. It tries to get the acknowledge message on some operation (I
guess it should be some cache operation).
You can see that IgniteClientDisconnectedException was thrown. In this
case, you can get the reconnect future and wait for the client reconnection:
https://apacheignite.readme.io/docs/clients-vs-servers#reconnecting-a-client
Please add try/catch blocks around your cache operation and add next logic:
|catch (IgniteClientDisconnectedException e) {
e.reconnectFuture().get(); // Wait for reconnect. // Can proceed and use
the same IgniteCompute instance. }|
I can't say why your client was disconnected. Highly likely it's because
of some network issues. You can try to take a look at server logs and
find there *NODE_LEFT *or *NODE_FAILED *messages.
BR,
Andrei
