HIVE_TABLE_NAME_ERROR

Error message

Current table name is

What it means

HiveTableUtils.getTableInfo parses the `table_name` config into a TablePath (database.table). The connector throws HIVE_TABLE_NAME_ERROR when either the database name or table name is missing, meaning the configured table name does not have the required `db.table` form. The connector cannot resolve the Hive metastore table without both parts.

Solutions

Set `table_name` to the fully qualified `database.table` form, e.g. `table_name = "default.my_table"`.
Check the HOCON config for typos, stray quotes, or an unrendered template variable in the table_name value.
If the value is built programmatically, validate it contains exactly one '.' with non-empty parts before calling getTableInfo.

Example fix

// before
table_name = "my_hive_table"
// after
table_name = "default.my_hive_table"

Defensive patterns

Strategy: validation

Validate before calling

String table = readonlyConfig.get(HiveBaseOptions.TABLE_NAME);
String[] parts = table == null ? new String[0] : table.split("\\.");
if (parts.length != 2 || parts[0].isEmpty() || parts[1].isEmpty()) {
    throw new IllegalArgumentException("table_name must be 'database.table', got: " + table);
}

Try / catch

try {
    Table t = HiveTableUtils.getTableInfo(readonlyConfig);
} catch (SeaTunnelRuntimeException e) {
    if (HiveConnectorErrorCode.HIVE_TABLE_NAME_ERROR.equals(e.getErrorCode())) {
        // log config value and fail fast with guidance to use db.table
    }
    throw e;
}

Prevention

Always write table_name as database.table in Hive connector configs.
Add a config pre-check in your deployment pipeline for the db.table pattern.
Render template variables before job submission and log the resolved value.

When it happens

Trigger: Calling HiveTableUtils.getTableInfo(readonlyConfig) where HiveBaseOptions.TABLE_NAME is null, a bare table name without a database prefix (e.g. "mytable"), or a malformed string like "db." or ".table" that yields a null databaseName or tableName from TablePath.of().

Common situations: User configures `table_name = "my_table"` instead of `"my_db.my_table"` in a Hive source/sink config; a placeholder template value was never substituted; extra/missing quotes or spaces around the value cause the split on '.' to fail.
