Stamatis Zampetakis commented on HIVE-26631:
--------------------------------------------
Thanks for the information [~haoweiliang] .
Below a few additional notes based on your observations.
The variables were introduced by HIVE-4766 (at this point thrift was at version
0.9.2) to prevent beeline from hanging when Thrift is overloaded. However, in
THRIFT-5297 (thrift 0.14.0) they decided to drop the configuration parameters
and simply drop the connection if server is too busy. With THRIFT-5297 in place
there is no risk of hanging but it is also not possible to configure how much
to wait before rejecting the connection.
>From a Hive perspective HIVE-25098 partially breaks HIVE-4766 so the former is
>a somewhat backward incompatible change.
> Remove unused variable requestTimeout and beBackoffSlotLength in the
> initServer method of the ThriftBinaryCLIService class

> Upgrade thrift from 0.13.0 to 0.14.1 in
> issuse(https://issues.apache.org/jira/browse/HIVE-25098)， The settings of
> requestTimeout and beBackoffSlotLength are removed for TThreadPoolServer.Args
> objects. However, variable requestTimeout and beBackoffSlotLength unused,
> better to clean up them and HiveConf:
> * hive.server2.thrift.exponential.backoff.slot.length
> * hive.server2.thrift.login.timeout
