>
> Currently when registering schemas in root schema, if a plugin throws an
> exception we fail the query. This causes every query to fail as every query
> needs a complete schema tree. Plugins could throw exceptions due to transient
> errors (storage server is temporarily not reachable).
> If a plugin throws an exception during schema registration, log an error,
> skip the plugin and continue registering schemas from rest of the plugins. If
> the user is querying tables from other plugins, the query should succeed. If
> the user is querying the tables in skipped plugin, a table not found
> exception is thrown.
