org.apache.hadoop.hbase.client.HTablePool$PooledHTable cannot be cast to org.apac


Java 向Hbase表插入数据报(org.apache.hadoop.hbase.client.HTablePool$PooledHTable cannot be cast to org.apac)

代码:


//1.create HTablePool

HTablePool hp=new HTablePool(con, 1000);

//2.get HTable from HTablepool

HTable ht=(HTable)hp.getTable(tName);


原因:现在应用的api版本号中pool.getTable返回的类型是HTableInterface ,无法强转为HTable

Java 向Hbase表插入数据报(org.apache.hadoop.hbase.client.HTablePool$PooledHTable cannot be cast to org.apac)


解决的方法:

 ht.put(put); 换成

hp.getTable(tName).put(put);
