----------------------------------------
[~isapego] Looks good to me.
> Thin clients: close query cursors on disconnect
> -----------------------------------------------
>
> Key: IGNITE-6330
> URL: https://issues.apache.org/jira/browse/IGNITE-6330
> Project: Ignite
> Issue Type: Bug
> Components: jdbc, odbc
> Affects Versions: 2.1
> Reporter: Pavel Tupitsyn
> Assignee: Igor Sapego
> Fix For: 2.3
>
>
> {{JdbcRequestHandler}} and {{OdbcRequestHandler}} store active cursors in
> {{qryCursors}} map. If client connection abruptly ends, these cursors are not
> closed properly.
> {{SqlListenerNioListener.onDisconnected}} should call
> {{SqlListenerConnectionContext.onDisconnected}}, and connection context
> should clean up all resources there.
