Navis commented on HIVE-3054:
-----------------------------
HiveServer2 keeps session/operations in spite of connection failure. No special
protocol change is not needed for session recovery If connection can be
re-established. But for hiveserver1, it's not possible without some
modifications.
> Simple reconnection support for JDBC

> Key: HIVE-3054
> URL: https://issues.apache.org/jira/browse/HIVE-3054
> Project: Hive
> Issue Type: Improvement
> Components: JDBC
> Affects Versions: 0.10.0
> Reporter: Navis
> Assignee: Navis
> Priority: Trivial
>
> Somehow when hive server is down, JDBC connections should be re-established
> by hand and it's not clean to implement on the outside of JDBC code.
> Session recovery could be also implemented if HiveServer2(HIVE-2935) is ready.
