Hash-aware view update causing lock ups in Hot Rod
--------------------------------------------------
Key: ISPN-1016
URL:
https://issues.jboss.org/browse/ISPN-1016
Project: Infinispan
Issue Type: Bug
Components: Cache Server
Affects Versions: 4.2.1.FINAL
Reporter: Galder ZamarreƱo
Assignee: Galder ZamarreƱo
Fix For: 4.2.2.BETA1, 4.2.2.FINAL, 5.0.0.BETA1, 5.0.0.FINAL
When encoding a Hot Rod response, if the encoder discovers that the client has an old
view, it decides that a new topology needs to be sent to the client. Now, when building
this view in distributed caches, the encoder checks whether in the new view, any of the
nodes hash ids has changed, and if so, it sends a cluster wide replace with the view
containing the new hash ids.
This seems to cause some deadlocks as shown in JBPAPP-6113 where one node is timing to
send the replace to other node, and another node is timing out doing the same. This needs
further thinking but have some ideas in mind...
On top of that, it appears that a failure here is causing problems the requests after
that, so some thinking needs to be done to see if that replace() call can be moved out of
there...
