I'd be surprised if this was interesting to anybody except those who already invested a lot in IBM z infrastructure.
Many large compagnies (bank, telecom...) are still based on mainframe and z/os. They want to move on Big Data technologies like Hadoop but not easy because a major IT gap.
IBM try to help with that move, many not the best solution because it's more Hadoop on Z/linux and not Z/os but still a interesting move from IBM to stay on the race.
