    ISPN004017: Could not fetch transport: org.infinispan.client.hotrod.exceptions.TransportException

    Nikhil Joshi Newbie

      I am accessing infinispan data grid 5.3 in clustered mode (setup on 2 nodes) from my application hosted on EAP 6.1.1.

      While carrying out following test I am getting an exception.


      1. Start both hot rod servers.

      2. Access servers using application hosted on EAP [infinispan.client.hotrod.server_list=HOST1:11222;HOST2:11222]. This is the only property defined in properties file, rest are default.

      3. Cache operations working fine so far

      4. Shutdown HOST1.

      5. Cache operations starts giving following exception, I was expecting the cache operations to work successfully on HOST2

      Notes:

      - Cache operations works fine in case where HOST2 is down and HOST1 is up. So it seems whichever host we define first in server_list if it goes down it could not recover from this excpetion until we make that server up. 

      - There is only one instance of RemoteCacheManager for this application which is initialized only once.

       

      Appreciate any inputs to resolve this issue.
