I’ve heard about MapR for a long time and haven’t given it much consideration vs. OSS stacks. I reconsidering my position and conduction some evaluations.
Why? MaprFS is a real POSIX File system that runs on Raw devices, not atop ext4, xfs, etc. It also runs natively, not in a JVM. It claims HDFS compliance and so should work with other Hadoop tools. It also has an integrated HBase API compatible data store and Kafka 0.9 API compatible pub/sub service. These are part of the base FS which should make things “better” than the rest. We’ll see.
If some of these things prove out, this could be a game changer for my perspective.
