Johndee Burks created HIVE-4549:
-----------------------------------
Summary: JDBC compliance change
Key: HIVE-4549
URL: https://issues.apache.org/jira/browse/HIVE-4549
Project: Hive
Issue Type: Improvement
Components: JDBC
Affects Versions: 0.10.0
Environment: Hive 0.10
Reporter: Johndee Burks
Priority: Trivial
The ResultSet returned by HiveDatabaseMetadata.getTables has the metadata
columns TABLE_CAT, TABLE_SCHEMA, TABLE_NAME, TABLE_TYPE, REMARKS. The second
column name is not compliant with the JDBC standard
(http://docs.oracle.com/javase/6/docs/api/java/sql/DatabaseMetaData.html#getSchemas()):
the column name should be TABLE_SCHEM instead of TABLE_SCHEMA.
Suggested fix in Hive
(org.apache.hive.service.cli.operation.GetTablesOperation.java) change from
private static final TableSchema RESULT_SET_SCHEMA = new TableSchema()
.addStringColumn("TABLE_CAT", "Catalog name. NULL if not applicable.")
.addStringColumn("TABLE_SCHEMA", "Schema name.")
.addStringColumn("TABLE_NAME", "Table name.")
.addStringColumn("TABLE_TYPE", "The table type, e.g. \"TABLE\", \"VIEW\",
etc.")
.addStringColumn("REMARKS", "Comments about the table.");
