> Attempting to connect an older version gfsh to a newer version JMX manager
> should fail
> --------------------------------------------------------------------------------------
>
> Key: GEODE-3946
> URL: https://issues.apache.org/jira/browse/GEODE-3946
> Project: Geode
> Issue Type: Bug
> Components: gfsh
> Reporter: Barry Oglesby
> Assignee: Kenneth Howe
> Priority: Trivial
>
> Currently, an older version of gfsh can connect to a newer version JMX
> manager, but when a command is invoked, it'll fail with a cryptic message.
> An example is:
> 9.1.1 JMX manager
> 9.0.3 gfsh
> Attempting to execute a query with this scenario logs a 'Could not parse
> command string' message:
> {noformat}
> gfsh>query --query='SELECT sauce FROM /data' --interactive=true
> Could not parse command string. query --query='SELECT sauce FROM /data'
> --interactive=true --step-name=SELECT_EXEC
> {noformat}
> Instead, gfsh should fail at connect time with an
> {{IncompatibleVersionException}} or something similar.
