While Spark has a learning curve of its own, the Scala-based framework has not only replaced Java-based MapReduce, but also eclipsed Hadoop in importance in the emerging big data ecosystem. vendor_id : GenuineIntel There’s also a large concentration of mainframes in banking, insurance, and healthcare, whereas IBM i has a stronger foothold in manufacturing, distribution, and retail. model : 63 “I don’t think we’re there yet in terms of running those things natively on i,” Bestgen says. physical id : 41 We have a distributed stack for across many types of applications. bogomips : 4000.06 cpu MHz : 2000.032 model : 63 Apache Spark provides high-level APIs in Java, Scala, Python and R.

IBM wants to keep those analytic workloads on the mainframe if at all possible, which is why it made Spark run natively. The widely held thinking within IBM is that the Linux route makes more practical sense – if Spark is to come to IBM i at all (which, as far as we know, hasn’t been decided).
