      Description

      Symptom

      When DROP TABLE a table, metadata of the table is generated to be able to import the dropped table again.
      However, the exported metadata name is '<table name>.metadata'.
      Since ImportSemanticAnalyzer allows only '_metadata' as metadata filename, user have to rename the metadata file to import the table.

      How to reproduce

      Set the following setting to hive-site.xml:

       <property>
         <name>hive.metastore.pre.event.listeners</name>
         <value>org.apache.hadoop.hive.ql.parse.MetaDataExportListener</value>
       </property>
      

      Then run the following queries:

      > CREATE TABLE test_table (id INT, name STRING);
      > DROP TABLE test_table;
      > IMPORT TABLE test_table_imported FROM '/path/to/metadata/file';
      FAILED: SemanticException [Error 10027]: Invalid path
