Description

It appears that the Hive Metastore does not properly migrate column statistics when renaming a table across databases. While renaming across databases is not supported in HiveQL, it can be done via the Metastore Thrift API.
The problem is that such a newly renamed table cannot be dropped (unless renamed back to its original database/name).

Here are steps for reproducing the issue.

1. From the Hive shell/beeline:

create database db1;
create database db2;
create table db1.mv (i int);
use db1;
analyze table mv compute statistics for columns i;

2. From a Java program:

  public static void main(String[] args) throws Exception {
    HiveConf conf = new HiveConf(MetaStoreClientPool.class);
    HiveMetaStoreClient hiveClient = new HiveMetaStoreClient(conf);
    Table t = hiveClient.getTable("db1", "mv");
    t.setDbName("db2");
    t.setTableName("mv2");
    hiveClient.alter_table("db1", "mv", t);
  }

3. From the Hive shell/beeline:

drop table db2.mv2;
