--------------------------------
Summary: Issues with connection and authentication with Apache Druid (was:
Possible bug with connection and authentication with Apache Druid)
> Issues with connection and authentication with Apache Druid
> -----------------------------------------------------------
>
> Key: CALCITE-5719
> URL: https://issues.apache.org/jira/browse/CALCITE-5719
> Project: Calcite
> Issue Type: Bug
> Components: avatica-go
> Reporter: Parag Jain
> Assignee: Francis Chuang
> Priority: Major
> Labels: avatica
>
> I have been using calcite-avatica-go driver to connect to Apache Druid and
> facing few issues -
> # In Go sql package when an idle connection is picked from the pool,
> *ResetSession* method is called on the connection. In the drivers
> implementation of this method
> [here|https://github.com/apache/calcite-avatica-go/blob/main/connection.go#L236],
> *registerConn* method is called which actually does an
> *OpenConnectionRequest* with the existing connectionId. On the Druid side it
> actually throws an exception
> [here|https://github.com/apache/druid/blob/master/sql/src/main/java/org/apache/druid/sql/avatica/DruidMeta.java#L823]
> saying the connection is already open. I checked other driver
> implementations like
> [postgres|https://github.com/jackc/pgx/blob/master/stdlib/sql.go#L307] and
> [mysql|https://github.com/go-sql-driver/mysql/blob/master/connection.go#L638]
> for ResetSession method and they actually don't open a new connection. So not
> sure about the reason for doing this here. Any thoughts on this ?
> # Username and pwd not being propagated in the JDBC context. Had to add the
> following code in the [Connect|
> https://github.com/apache/calcite-avatica-go/blob/main/driver.go#L64] method
> of driver.go
> {code:java}
> if config.avaticaUser != "" {
> c.Info["user"] = config.avaticaUser
> }
> if config.avaticaPassword != "" {
> c.Info["password"] = config.avaticaPassword
> } {code}
