Continuity mistake: 9-4 "Man on Fire": McGarrett's blackboard already lists plutonium as the poison source before Dr. Ormsbee enters to inform him that plutonium was the poison source.
... And They Painted Daisies On His Coffin - S1-E7
Continuity mistake: When McGarrett arrests Big Chicken at the end of the episode, he twists Chicken's right arm up behind his back, but then in the next shot, Chicken's arm is up above his head on the door in front of him. (00:49:10)
Continuity mistake: As Kono talks to Johnny Kalama in the students' apartment, an orange lava lamp sits on the shelf between them. Each time the camera angle reverses, the wax bubbles in the lamp are very noticeably in different positions and configurations. (00:41:00)
Continuity mistake: Danno, posing as a photographer on the beach, snaps the shutter at a bikini-clad girl and quips, "I only wish I had some film." Seconds later, he takes a picture of the suspects that's then used to identify them. The scene is continuous, and at no time did he ever load film into the empty camera, nor did he have another one. (00:34:30)
The Bomber and Mrs. Moroney - S3-E22
Continuity mistake: The HPD snipers watch McGarrett's office window, trying to get a clear shot at Collins. In camera views from inside the office, there's a coat rack with a hanger on it standing in front of the window. But in all the shots from the snipers' POV, the coat rack isn't there. (00:40:00)
Continuity mistake: Danno kicks one of the bad guys out of the van, leaving the rear doors swinging open. But when the shot immediately cuts to an exterior view of the speeding van, the doors are tightly shut again. (00:35:00)
Continuity mistake: When McGarrett and Danno question Frank's daughter, she has her hands clasped in front of her. When the shot cuts, her arms are suddenly extended down at her sides instead. (00:29:50)
Continuity mistake: Kealoha puts his gun back in its shoulder holster before walking a few feet across the parking lot to meet McGarrett. When we cut to a two-shot of them, Kealoha puts his gun away all over again. (00:32:30)
... And They Painted Daisies On His Coffin - S1-E7
Continuity mistake: McGarrett strong-arms Tommy-Tommy, the Hawaiian fence, on the beach, and the guy gets sand all over his face during their scuffle. When McGarrett pulls him to his feet, the sand is still there. But in the next shot, all but a small patch near his temple has disappeared. (00:32:40)
Continuity mistake: Auston leaves the unconscious Dan Williams lying on his back. But in the next shot, Danno's lying on his side. Later, the seriously wounded Danno instantly changes positions between shots several more times, switching from face down to face up on the floor. (00:02:30 - 00:32:00)
Continuity mistake: Throughout first season: Due to stock footage spliced in from the pilot film, McGarrett's '68 4-door Mercury sedan often peeled away from the Ionali palace and then turned into a '67 2-door coupe as it cruised down Honolulu's streets.
Continuity mistake: Throughout the episode, Larsen's first name is "Dan." But in the end credits, he's listed as "Steve." (00:49:00)
Murder with a Golden Touch - S6-E20
Continuity mistake: Danno reports that the salvage boat is "The Pacific Pearl." But when we see the vessel, the name painted on its hull is "Louise."
Continuity mistake: Stock footage turns McGarrett's 1970 Mercury into his old 1966 model when he drives out of the Iolani Palace parking lot. (00:31:00)
Continuity mistake: There's much too abrupt a transition between Reese falling into the water and his body suddenly being back on the dock. As there's no time lapse implied at all, he seems to reappear on shore by magic. At least a brief shot of the body being fished out of the water might have helped. (00:49:40)
Pray Love Remember, Pray Love Remember - S1-E14
Continuity mistake: Danno walks several feet into McGarrett's office to make a report. Though there's no break in the dialogue and no time for him to have moved, the shot cuts and he's suddenly standing outside the door as they finish their conversation. (00:02:45)
Continuity mistake: During the stand-off, Big Chicken is standing several inches to McGarrett's left, on the other side of a seam in the concrete wall. When the shot cuts to a closer angle, Chicken is instantly close enough to touch shoulders with McGarrett, and is now blocking the concrete seam. (00:25:30)
Continuity mistake: Aboard the boat, when Danno draws his gun, both his suit and his tie change colors and patterns completely between takes.
Continuity mistake: At the end, Krenter is shot during the final gun battle on the beach. Between takes, his body and the deflated rubber raft that was also on the sand both disappear. (00:48:00)
Continuity mistake: Although the plane making an emergency landing is repeatedly referred to as a jet, the aircraft we see in the air (and later landing) is a prop job. (00:03:00)
Answer: He was fired. He never really appreciated his character. He felt Kono was portrayed as a big dumb Hawaiian and that the stereotype was racist. He also felt underutilized. He was fired after a heated argument with the show's publicist regarding his character. It seems there's not much details given regarding the incident or the firing, so it's seems possible he upset the show's producers as well.

No he said something derogatory about one of the Jewish producers that's why he was fired.
