蜂巢即使显示MSCK REPAIR TABLE后也不会显示表数据

Question

我有一个场景：外部配置单元分区表的配置单元数据类型更改为n1。执行以下步骤后，我没有得到数据。

---

我遵循以下步骤：

>>created new table n2 with new datatype
>>dynamically inserted data in n2 from original table n1
>>Then follows below steps to rename the table to original name :n1
>>ALTER TABLE n1 DROP IF EXISTS PARTITION (partition_date>'0');
>>hadoop fs -rm -r hdfs://FajitaDevelopment/data/gfctwnsg/staging/hive/gfctwnsg_staging/n1/partition_date*/*
>>MSCK repair table n1;
>>DROP TABLE n1;
>>ALTER TABLE n2 RENAME TO n1;
>>hadoop fs -rm -r hdfs://FajitaDevelopment/data/gfctwnsg/staging/hive/gfctwnsg_staging/n1/*
>>hadoop fs –mv hdfs://FajitaDevelopment/data/gfctwnsg/staging/hive/gfctwnsg_staging/n2/*  hdfs://FajitaDevelopment/data/gfctwnsg/staging/hive/gfctwnsg_staging/n1
>>MSCK repair table n1;
>>Alter table n1 SET LOCATION   'hdfs://FajitaDevelopment/data/gfctwnsg/staging/hive/gfctwnsg_staging/n1' ;
        MSCK repair table n1;

********，请让我知道，为什么我在重命名表后没有获取数据。

表指向：**** hdfs：// FajitaDevelopment / data / gfctwnsg / staging / hive / gfctwnsg_staging / n1

    >> `MSCK REPAIR TABLE n1;`
    >> `hadoop fs -ls -R hdfs://FajitaDevelopment/data/gfctwnsg/staging/hive/gfctwnsg_staging/n1`
