Hi, which Ignite's version do you use?

*Local* queries are prohibited on client nodes since they do not store data.

The check was added within task [1] and included in Ignite 2.7 release.

Hi Guys,

I am also running into same issue where I am doing local query

            SqlFieldsQuery query = new SqlFieldsQuery(sql);
            query.setLocal(true);
            FieldsQueryCursor<List&lt;?>> fq = cache.query(query);


This leads to same exception stack trace. 

Is there any workaround where I would like query to be only issued against
the rows that are cached locally on the query node.

Thank you very much
Prashant Patel
