Description

The first run of python client returns empty result set, all consequence runs just hang:

from pyignite import Client, GenericObjectMeta
import collections
from pyignite.datatypes import  *

if __name__ == '__main__':
    client = Client()
    client.connect('localhost', 10800)
    cache = client.get_cache('Batch')
    #client.register_binary_type(BatchConfigurationPK)
    #client.register_binary_type(BatchConfiguration)
    result = cache.scan()
    print([b for b in result])

public class ObjectTest {

  @QuerySqlField
  private String field1;

  @QuerySqlField
  private String field2;

  @QuerySqlField
  private String field3;

  @QuerySqlField
  private String field4;

  @QuerySqlField
  private Boolean enabled;


  public ObjectTest(String field1, String field2, String field3) {
    this.field1 = field1;
    this.field2 = field2;
    this.field3 = field3;
  }
}

public static void main(String[] args) throws IgniteException {
        Ignite ignite = Ignition.start("examples/config/example-ignite.xml");

        IgniteCache cache = ignite.getOrCreateCache("Batch");

        for (int i = 0; i < 100; i++) {
            cache.put(i, new ObjectTest("" + i, "" + i, "" + i));
        }
    }
