In a saucepan, stir together pineapple juice, brown sugar, Dijon mustard and ground cloves. Bring to a boil and then simmer, stirring occasionally, until the mixture becomes slightly syrupy (about 10-15 minutes). Set aside.
Line a roasting pan with aluminum foil. Place ham in the pan, flat-side down. Using a sharp knife, score surface of ham with ¼-inch-deep cuts in a diamond pattern. Arrange pineapple and cherries evenly on ham; secure with wooden toothpicks. Spoon some of the glaze over the ham.
Bake at 325°F for a total of about 2 - 2 ½ hours, basting with the extra glaze and pan juices every 30 minutes. Shield the ham loosely with aluminum foil when it reaches the desired color, to prevent excess browning. The ham is done when a meat thermometer inserted into the thickest portion registers 140°F.
Let the ham stand for at least 15 minutes, remove toothpicks, and carve.

Notes
How Long to Bake a Pre-Cooked Ham: You can use this recipe with just about any size ham. A good rule of thumb to remember is that a smoked ham bakes at 325°Ffor 15 to 20 minutes per pound. For instance, I roasted an 8-lb. ham for 2 hours. As always, an instant read thermometer is the best way to know when your ham is done. When the temperature registers 140°F, it's safe to pull the meat out of the oven.
Glaze the ham before, during and after baking! The glaze and pan juices add flavor and moisture to the meat as it cooks, so I recommend pour, brush, or baste with the glaze every 30 minutes or so.
Should you cover a ham when you bake it? I find that it works best to start with the ham uncovered. This gives the glaze a chance to caramelize on the outside of the ham, adding beautiful color and flavor to the meat. Keep an eye on the ham, though. When it reaches the desired color, you'll want to loosely shield the ham with foil to prevent it from getting too dark as the meat continues to heat through.
How Much Ham Per Person: A good rule of thumb is to assume about ¾ lb. per person for a bone-in ham, so an 8 lb. ham will feed about 10-11 people.
