Hi    We run Cloudera based hadoop cluster - 5.11 (not hortonworks) and currently we added 5 new impala daemon nodes. (Impala version 2.8).   After adding new nodes, things looked fine ,but after 7-8 hours we are getting below errors when the impala co-ordinator tried to connect to the newly added nodes.  Please help resolving it as we are blocked in production   Error : Sender timed out waiting for receiver fragment instance Detailed error : I0506 20:16:55.660058 72446 coordinator.cc:1417] CancelFragmentInstances() query_id=d6447c0a5ed591c4:47ac776800000000, tried to cancel 35 fragment instances I0506 20:16:55.663775 72446 coordinator.cc:756] Query id=d6447c0a5ed591c4:47ac776800000000 failed because fragment id=d6447c0a5ed591c4:47ac776800000006 on host=hadoop-slave22.use1.data.ripple.com:22000 failed.
