[jira] [Created] (KUDU-2027) Connection negotiation timeout to tablet server is treated as unretriable error on scan operations

Alexey Serbin created KUDU-2027:
-----------------------------------

             Summary: Connection negotiation timeout to tablet server is treated as unretriable error on scan operations
                 Key: KUDU-2027
                 URL: https://issues.apache.org/jira/browse/KUDU-2027
             Project: Kudu
          Issue Type: Bug
    Affects Versions: 1.3.0, 1.2.0, 1.0.0, 1.4.0
            Reporter: Alexey Serbin
            Assignee: Alexey Serbin


In the case that the leader tablet server is up but "frozen", the client will get a connection negotiation timeout while starting or continuing a scan operation.  The code in KuduScanner::Data::OpenTablet() does not allow the scan operation to failover to different tablet server even if operation timeout setting would allow to wait for a new leader to be elected.

So, the client gets a failure even if there has been a leader re-election within the client-provided deadline.
