Apache Ignite JDBC Thin Client Does not work with Existing Cache - ignite

Question

I have created an Ignite cache "contact" and added "Person" object to it.
When I use Ignite JDBC Client mode I am able to query this cache. But when I implement JDBC Thin Client, it says that the table Person does not exist.
I tried the query this way:
Select * from Person
Select * from contact.Person
Both did not work with Thin Client. I am using Ignite 2.1.
I appreciate your help as how to query an existing cache using Thin Client.
Thank you.

Cache Configuration in the Server Side of the Code
CacheConfiguration<Long, Person> cc = new CacheConfiguration<>(cacheName);
cc.setCacheMode(CacheMode.REPLICATED);
cc.setRebalanceMode(CacheRebalanceMode.ASYNC);
cc.setIndexedTypes(Long.class, Person.class);
cache = ignite.getOrCreateCache(cc);
Thin Client JDBC URL
Class.forName("org.apache.ignite.IgniteJdbcThinDriver");
// Open the JDBC connection.
Connection conn = DriverManager.getConnection("jdbc:ignite:thin://192.168.1.111:10800");
Statement st = conn.createStatement();

Answer 1

If you want to query data from an existing cache using SQL, you should specify an SQL schema in the cache configuration. Add the following code before the cache creation:
cc.setSqlSchema("PUBLIC");
Note that you have persistence configured, so when you do ignite.getOrCreateCache(cc); the new configuration won't be applied, if a cache with this name is already persisted. You should, for example, remove persistence data or use createCache(...) method instead.
