Search 9 Sudoku (Daily Sudoku League #29)

Indian Sudoku Championship 2014 is happening on coming weekend. "Search 9 Sudoku" is one of the new variation appearing in ISC 2014. This puzzle I have created for the practice of this championship.

Moreover this "Search 9 Sudoku" is my 29th contribution for The League of Extraordinary Ladies and Gentlemen.

Rules of Search 9 Sudoku

Classic Sudoku Rules apply. Additionally each arrow points to the 9 in the respective row or column. The number in the cell with the arrow is the distance from the cell to the 9 in this row or column.
