Dave Chappelle - RIPPED BY HARTFORD MAYOR ... 'Quit Whining'

The mayor of Hartford, Connecticut is firing back at Dave Chappelle -- telling the comic to QUIT BITCHING about his city ... and get on with his life.

"Dave Chappelle needs to quit whining, do his job and try some yoga," Mayor Pedro Segarra tweeted this morning.

The Mayor is clearly referring to Chappelle's anti-Hartford rant ... when he called for North Korea to hit the Connecticut city with a nuclear strike after the "young, white alcoholic" crowd heckled him during a show last week.

"His recent remarks were immature and inappropriate," Segarra tells TMZ ... adding, "[He] should stick to his job, give the fans what they paid for and not disparage the good people of Hartford."

Snap.
