"Arunkumar has just joined. Karnataka won various tournaments under him. He is a team-oriented man. I think he will do well for us," Hyderabad Cricket Association (HCA) president G Vivekanand told PTI.
Arunkumar, a former First Class cricketer, took over from Bharat Arun, who has joined as bowling coach of the national cricket team.
Under his guidance since 2012-13, Karnataka won the Ranji Trophy, the Irani Cup and the Vijay Hazare Trophy.
The 42-year-old right-handed batsman made his debut in First Class cricket in 1993-94 and hung his boots in 2008.
