Any body know why Peter Hyams, who directed 2010, chose not do a film version of the book, and essentially rewrote it for the screen ?
The book is much more interesting than the film 2010, and a lot more uplifting.

The only response I can offer to your query is a note from 2010's wiki:
When Clarke published his novel 2010: Odyssey Two in 1982, he telephoned Stanley Kubrick, and jokingly said, "Your job is to stop anybody [from] making it [into a movie] so I won't be bothered." Metro-Goldwyn-Mayer (MGM) subsequently worked out a contract to make a film adaptation, but Kubrick had no interest in directing it. However, Peter Hyams was interested and contacted both Clarke and Kubrick for their blessings:
I had a long conversation with Stanley and told him what was going on. If it met with his approval, I would do the film; and if it didn't, I wouldn't. I certainly would not have thought of doing the film if I had not gotten the blessing of Kubrick. He's one of my idols; simply one of the greatest talents that's ever walked the Earth. He more or less said, 'Sure. Go do it. I don't care.' And another time he said, 'Don't be afraid. Just go do your own movie.'
While he was writing the screenplay in 1983, Hyams (in Los Angeles) began communicating with Clarke (in Sri Lanka) via the then-pioneering medium of e-mail. The two would discuss the planning and production of the film on an almost daily basis using this method. Their correspondence was published in 1984 as The Odyssey File: The Making of 2010. The book illustrates Clarke's fascination with the new method of communication, and also includes Clarke's list of the top science fiction films ever made. In order to give the publishers enough lead-time to have it available for the release of the movie, the book terminates while the movie is still in pre-production. At the point of the last e-mail, Clarke had not yet read the script, and Roy Scheider was the only actor who had been cast
