Any ideas what's causing this? What additional information can I provide to help with this?

Side question: what is a difference between coordinator and executor?

Re: Impala ECONNRESET errors

I will refer you to https://www.cloudera.com/documentation/enterprise/5-14-x/topics/impala_dedicated_coordinator.html

 

Essentially, an executor does the "work", and a coordinator manages executors and distributes the work.

Were you able to fix this issues?

 

I am seeing this same issue after patching a couple of our datanodes that impala is running on. If I stop the impala service on those nodes that have been patched everything works fine. 

 

what CDH version are you running?

and what kernal version are you running?

 

I am running CDH - 5.13.3

Kernal version before patching - kernel-2.6.32-696.20.1 --> kernel-2.6.32-754.3.5
