---------------------------------------
Summary: JDBC: HttpClient should retry one more time on
NoHttpResponseException
Key: HIVE-16107
URL: https://issues.apache.org/jira/browse/HIVE-16107
Project: Hive
Issue Type: Bug
Components: HiveServer2, JDBC
Affects Versions: 2.1.1, 2.0.1
Reporter: Vaibhav Gumashta
Assignee: Vaibhav Gumashta
Hive's JDBC client in HTTP transport mode doesn't retry on
NoHttpResponseException. We've seen the exception being thrown to the JDBC end
user when used with Knox as the proxy, when Knox upgraded its jetty version,
which has a smaller value for jetty connector idletimeout, and as a result
closes the HTTP connection on server side. The next jdbc query on the client,
throws a NoHttpResponseException. However, subsequent queries reconnect, but
the JDBC driver should ideally handle this by retrying.
