Native metadata cloud not be imported if default values of import properties are used:

Phoenix driver seems does not support unique indexes (https://github.com/apache/phoenix/blob/master/phoenix-core/src/main/java/org/apache/phoenix/jdbc/PhoenixDatabaseMetaData.java#L690) and returns every time the same ResultSet. After first table, Teiid closes it and next loop fails (https://github.com/teiid/teiid/blob/790e0da722de6f49685ce761302e54772843b917/connectors/translator-jdbc/src/main/java/org/teiid/translator/jdbc/JDBCMetdataProcessor.java#L666).

The empty ResultSet is being used across all the PhoenixDatabaseMetaData class:
getProcedures(...), getIndexes(...), getImportedKeys(...), getFunctions(...), ...
