-----------------------------------
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.
