-------------------------------------
Hi [~ashutoshc],
Sorry for late.
I'm trying to write a testcase, but it's a bit hard to add a case for this
feature.
When a table is dropped, this feature will dump a metadata in a directory which
contains current datetime like
/user/sho/test_table.2013-04-05-20-13-14/test_table.metadata .
I can't write IMPORT FROM query against the dynamic path.
Do you have any idea to solve this problem?
Thanks,
Sho

> h2. 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.
> h2. How to reproduce
> Set the following setting to hive-site.xml:
> {code}
> <property>
> <name>hive.metastore.pre.event.listeners</name>
> <value>org.apache.hadoop.hive.ql.parse.MetaDataExportListener</value>
> </property>
> {code}
> Then run the following queries:
> {code}
> > 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
> {code}
