--------------------------------------------
Summary: JDBC HttpClient should retry for idempotent and unsent
http methods
Key: HIVE-24786
URL: https://issues.apache.org/jira/browse/HIVE-24786
Project: Hive
Issue Type: Bug
Affects Versions: 4.0.0
Reporter: Prasanth Jayachandran
Assignee: Prasanth Jayachandran
When hiveserver2 is behind multiple proxies there is possibility of "broken
pipe", "connect timeout" and "read timeout" exceptions if one of the
intermediate proxies or load balancers decided to reset the underlying tcp
socket after idle timeout. When the connection is broken and when the a query
is submitted after idle timeout from beeline (or client) perspective the
connection is open but http methods (POST/GET) fails with socket related
exceptions. Since these methods are not sent to the server these are safe for
client side retries.
