Sho Shimauchi created HIVE-4299:
-----------------------------------
Summary: exported metadata by HIVE-3608 cannot be imported because
of wrong file name
Key: HIVE-4299
URL: https://issues.apache.org/jira/browse/HIVE-4299
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.11.0
Reporter: Sho Shimauchi
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}
