Why are some portions of tape backup workloads being redirected to Hadoop clusters today?
What will be an ideal response?
• First, while it may appear inexpensive to store data on tape, the true cost comes with the difficulty of retrieval. Not only is the data stored offline, requiring hours if not days to restore, but tape cartridges themselves are also prone to degradation over time, making data loss a reality and forcing companies to factor in those costs. To make matters worse, tape formats change every couple of years, requiring organizations to either perform massive data migrations to the newest tape format or risk the inability to restore data from obsolete tapes.
• Second, it has been shown that there is value in keeping historical data online and accessible. As in the clickstream example, keeping raw data on a spinning disk for a longer duration makes it easy for companies to revisit data when the context changes and new constraints need to be applied. Searching thousands of disks with Hadoop is dramatically faster and easier than spinning through hundreds of magnetic tapes. Additionally, as disk densities continue to double every 18 months, it becomes economically feasible for organizations to hold many years' worth of raw or refined data in HDFS.

Heather owns a hair accessory company. She is looking to negotiate with her fabric supplier, which provides swimsuit material scraps, to reach a mutually beneficial agreement. Heather wants the supplier to consistently provide it with high-quality fabrics at a fair price within the allotted time frames. The fabric supplier would also be able to sell its otherwise unused scraps. The fabric supplier agrees and a formal contract is arranged. In the end, Heather has negotiated a long-term contract with the fabric supplier at a fair price, and the fabric supplier is guaranteed a new stream of business from Heather. Which type of bargaining does this scenario illustrate?

Sovereign Immunity. Nuovo Pignone, Inc, is an Italian company that designs and man-ufactures turbine systems. Nuovo sold a turbine system to Cabinda Gulf Oil Co (CABGOC). The system was manufactured, tested, and inspected in Italy, then sent to
Louisiana for mount-ing on a platform by CABGOC's contractor. Nuovo sent a representative to consult on the mounting. The platform went to a CABGOC site off the coast of West Africa. Marcus Pere, an instrument technician at the site, was killed when a turbine within the system exploded. Pere's widow filed a suit in a federal district court against Nuovo and others. Nuovo claimed sovereign immunity on the ground that its majority shareholder at the time of the explosion was Ente Nazionale Idrocaburi, which was created by the government of Italy to lead its oil and gas exploration and development. Is Nuovo exempt from suit under the doctrine of sovereign immunity? Is it subject to suit under the "commercial activity" exception? Why or why not?
