> If Thin Client authentication is disabled on cluster, JDBC Thin Driver
> disallows supplying of login/password
> ------------------------------------------------------------------------------------------------------------
>
> Key: IGNITE-8701
> URL: https://issues.apache.org/jira/browse/IGNITE-8701
> Project: Ignite
> Issue Type: Bug
> Components: jdbc
> Affects Versions: 2.5
> Reporter: Ilya Kasnacheev
> Assignee: Vladimir Ozerov
> Priority: Critical
> Fix For: 2.6
>
>
> Previously, Ignite JDBC clients would just ignore supplied login and password.
> In 2.5, Ignite Thin JDBC driver will instead fail with following error:
> {code}
> The requested operation could not be performed due to the following error :
> Handshake failed [driverProtocolVer=ClientListenerProtocolVersion [major=2,
> minor=5, maintenance=0], remoteNodeProtocolVer=ClientListenerProtocolVersion
> [major=2, minor=5, maintenance=0], err=Handshake error: Can not perform the
> operation because the authentication is not enabled for the cluster.]
> {code}
> when connecting to the cluster where authentication is disabled.
> This represents a *breaking change* in Apache Ignite API.
> Note that many tools (such as Informatica) insist on providing non-blank
> username and-or password for JDBC connections. This will mean they *no longer
> work* with Apache Ignite with no apparent workaround.
> My suggestion is to ignore login/password for JDBC Thin connections when
> authentication is not enabled for cluster.
