> There are some methods that Tajo cannot support. getPrimaryKeys,
> getExportedKeys, and getImportedKeys are examples. Currently, these methods
> cause SQLFeatureNotSupportedException. But, they should return an empty list
> instead of the exception. This patch fixes this problem.
> In addition, this patch fixes some potential deadlock problem in
> NettyClientBase and NettyServerBase.
