MapR File System selected by SAP for cloud storage layer
MapR’s file system was its original differentiator in the Hadoop market: unlike standard HDFS, which is optimized for reading, and supports writing to a file only once, MapR-FS fully supports the read-write capabilities of a conventional file system. That still doesn’t explain why SAP would use it for broader purposes, of course.
But Vikram Gupta, Senior Director of Product Management at MapR, explained to me that, far from being just an enhanced version of HDFS, MapR-FS was in fact implemented as a standard file system from the get-go. After the core file system was developed, an HDFS-compatible interface was built on top of it, allowing MapR to swap it into its Hadoop distro as a replacement for generic HDFS.
