(8.0.z) HotRod calls to remote caches use outdated topology information

XMLWordPrintable

      One interoperability test between EAP 8 and RHDG on OpenShift is failing.

      EAP 8 cluster instances are configured to use the remote RHDG cluster for a distributed cache. Specifically, the test persists ditributed timers status on the cache, as per EAP7-1417, but using a remote Infinispan.

      During the test one RHSG pod is stopped, in order to verify the timer "persistence" service fail-over mechanism, which actually takes place.

      Despite this, we noticed an issue: the logs show that one - or more - EAP instances perform a call to Infinispan via HotRod by using an IP which is no longer listed as part of the cluster topology, and after having received the up to date topology.

      • Working EAP 8 pod, using up to date information and showing no issues in Infinispan calls:

      This affects EAP 8 CR 1, and is filed as a blocker targeting EAP 8 GA for two reasons:
      1. it could affect the Infinispan subsystem outside of the scope of the RFE which has been tested
      2. to be considered for fix before EAP 8 GA.
