[jira] [Created] (IMPALA-5345) Under stress, some TransmitData() RPCs are not responded to

Henry Robinson created IMPALA-5345:
--------------------------------------

             Summary: Under stress, some TransmitData() RPCs are not responded to
                 Key: IMPALA-5345
                 URL: https://issues.apache.org/jira/browse/IMPALA-5345
             Project: IMPALA
          Issue Type: Bug
    Affects Versions: Impala 2.10.0
            Reporter: Henry Robinson
            Assignee: Henry Robinson
            Priority: Critical


Under stress conditions on two separate clusters (one secure, one not), I've seen some {{TransmitData()}} RPCs stay unresponded to forever, blocking the query's completion. The RPCs are seen by the recipient, but are not in the pending sender list.

Need to test further to see if this is related to the fix for IMPALA-5093 or if a response is dropped on some path if an row batch is 'retried' from the pending sender list.
