Ignite thin Client unstable behavior

I am newbie to ignite and trying to play around with the example https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/client/ClientPutGetExample.java

i first tried the example with one server node and executed the client everything work fine. then i started a second node with the following config 

IgniteClient igniteClient = Ignition.startClient(new ClientConfiguration().setAddresses("127.0.0.1:10800","127.0.0.1:10801" )))
with CacheMode.REPLICATED;

i re-run the code it work fine, then i kept the same config and i shut down one of the nodes then i re-run the code the result is unstable sometimes it gives me Ignite cluster is unavailable sometimes it gives me an empty cache

  • Thin client put-get example started.
  • Created cache [put-get-example].
  • Loaded [null] from the cache.

1-as per the documentation ignite thin client is supposed to failover one of the running nodes. 2- why the cache is note replicated? is there something that i am missing here
thank you for your help

Solution

  • This looks like IGNITE-11599 - Thin Client will not failover properly if some of addresses were not up when it started.

    It is fixed recently but did not get in any released versions. I'm afraid you will have to work around it by doing manual failovers.
