[jira] [Created] (KUDU-1409) Make krpc call timeouts more resistant to process pauses

Todd Lipcon created KUDU-1409:
---------------------------------

             Summary: Make krpc call timeouts more resistant to process pauses
                 Key: KUDU-1409
                 URL: https://issues.apache.org/jira/browse/KUDU-1409
             Project: Kudu
          Issue Type: Improvement
          Components: rpc
    Affects Versions: 0.8.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


In stress testing Impala on Kudu I've seen various RPC timeouts that turn out to be due to pauses on the client side. In particular, scenarios like https://issues.cloudera.org/browse/IMPALA-2800 can cause the memory allocator inside Impala to block for several seconds, and that might cause us to think we missed a timeout.

We should be more resilient to this sort of "false" timeout.
