我在嘗試合併其編號對應的數據存儲區實體已經匹配在HBase的實體時除外：Datanuclues合併在HBase的不工作（序列化（獨立）對象）

當試圖合併的實體。
與此相關的異常的代碼是：
System.out.println("Attempting to store data:" + value);
EntityManagerFactory emf = Persistence.createEntityManagerFactory("adimpression_ilikeplaces_war_1.6-SNAPSHOTPU_DN");
System.out.println("Obtained EntityManagerFactory.");
EntityManager em = emf.createEntityManager();
System.out.println("Obtained EntityManager.");
em.getTransaction().begin();
System.out.println("Began Transaction.");
em.merge(value);
System.out.println("Persisted data.");
em.getTransaction().commit();
System.out.println("Committed Transaction");
其中
em.merge(value);
是線39即AbstractHCMapStore.java:39。
我試圖合併的實體是一個新的實體，即使用java new關鍵字創建，並且以前不從數據庫中獲取。
任何幫助將不勝感激。
在此先感謝！
