Folgende Ausnahme tritt auf, wenn Apache verwendet, zünden Data Grid mit Schema-Import-Dienstprogramm. Eine Tabelle "Mitarbeiter" wurde mit dem Primärschlüssel "emp_no" als Spaltenname erstellt. generiert pojo Klassen und Konfiguration mit Apache zünden Schemaimport-Dienstprogramm. habe versucht, ein Beispielprogramm auszuführen, das mit der Distribution geliefert wird. Danach die Ausnahme. Apache Ignite Version ist: 1.5.0-finalAusnahme bei der Verwendung des Primärschlüssels mit "Unterstrich" -Zeichen in Apache zünden
