MapR Valuable Features

Founder at Chicago area Hadoop User Group (CHUG)
MapR’s strength comes from their file system. Because they start with the raw disk, they are able to expose the storage through various APIs and have the ability to lockdown and secure the file system better than the Apache derivatives, which store the file blocks above the Linux file system. Because of MapR’s POSIX compliant file system, they can support read/write files over the WORM storage of their competitors. In addition, they remodeled how to track and store the blocks. So the NameNode isn’t a single point of failure and you can store a magnitude of multiple orders of small files before you can cause a volume to have issues. Note: This is a cluster volume, not the entire cluster. Fill up the NameNode with lots of small files upon an Apache release, and you lose the entire cluster. View full review »
