-----------------------------------------
Summary: Fix how to confirm the RDBMS product name at Metastore.
Key: HIVE-11123
URL: https://issues.apache.org/jira/browse/HIVE-11123
Project: Hive
Issue Type: Bug
Components: Metastore
Affects Versions: 1.2.0
Environment: PostgreSQL
Reporter: Shinichi Yamashita
Assignee: Shinichi Yamashita
I use PostgreSQL to Hive Metastore. And I saw the following message at
PostgreSQL log.
{code}
< 2015-06-26 10:58:15.488 JST >ERROR: syntax error at or near "@@" at
character 5
< 2015-06-26 10:58:15.488 JST >STATEMENT: SET @@session.sql_mode=ANSI_QUOTES
< 2015-06-26 10:58:15.489 JST >ERROR: relation "v$instance" does not exist at
character 21
< 2015-06-26 10:58:15.489 JST >STATEMENT: SELECT version FROM v$instance
< 2015-06-26 10:58:15.490 JST >ERROR: column "version" does not exist at
character 10
< 2015-06-26 10:58:15.490 JST >STATEMENT: SELECT @@version
{code}
When Hive CLI and Beeline embedded mode are carried out, this message is output
to PostgreSQL log.
These queries are called from MetaStoreDirectSql#determineDbType. And if we use
MetaStoreDirectSql#getProductName, we need not to call these queries.
