Question

为了将hive与HBASE集成，我在hive中创建了下表。它已成功创建，我可以直接从HIVE和HBASE访问该表。

问题是当我从HIVE向表中插入覆盖数据时，我只看到数据出现在HBASE中。当我从Hive执行SELECT COUNT（*）FROM T_PONNMS_ONT_4时，它返回0.然而，当我从同一个表的HBASE查询记录计数时，显示所有5000万条记录。是否有这种情况的原因？

通过HIVE将数据插入HBASE表

CREATE TABLE IF NOT EXISTS T_PONNMS_ONT_4
(
TRANSACTIONORIGIN STRING,
TRANSACTIONID INT,
TRANSACTIONTIME STRING,
TRANSACTIONTYPE STRING,
ONT_UNIQUEID STRING,
ONT_SHELFNUM STRING,
ONTNUM STRING,
ONT_SERIALNUM STRING,
ONT_VENDOR STRING,
ONT_MODEL STRING,
ONT_STATUS STRING)
PARTITIONED BY (FILENAME STRING, TRANSACTION_DATE STRING)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ('hbase.columns.mapping' = 'cf:TRANSACTIONORIGIN,
                                                 cf:TRANSACTIONID,
                                                 cf:TRANSACTIONTIME,
                                                 cf:TRANSACTIONTYPE,
                                                 :key,
                                                 cf:ONT_SHELFNUM,
                                                 cf:ONTNUM,
                                                 cf:ONT_SERIALNUM,
                                                 cf:ONT_VENDOR,
                                                 cf:ONT_MODEL,
                                                 cf:ONT_STATUS')
TBLPROPERTIES ('hbase.table.name' = 'T_PONNMS_ONT_4');

HIVE＆GT; SELECT COUNT（*）FROM T_PONNMS_4; 好 0 时间为0.241

HBASE＆GT;计数＆＃39; T_PONNMS_ONT_4＆＃39; 返还5000万

Hive + HBase集成：查询时数据显示在HBASE中，未显示在HIVE中
