Do you mind adding a couple of simple unit tests to TestTableName as well. Thanks.

> In the class TableName,
> {code}
> public static byte [] isLegalFullyQualifiedTableName(final byte[] tableName) {
> ...
> int namespaceDelimIndex = ...
> if (namespaceDelimIndex == 0 || namespaceDelimIndex == -1){
>   isLegalTableQualifierName(tableName);
> } else {
> ...
> {code}
> That means, for example, giving ":a" as the argument throws an exception which says invalid qualifier, instead of invalid namespace.
> Also, TableName.valueOf(String) and valueOf(byte[]) can create an instance with empty namespace, which is inconsistent.
