glusterfs vs hdfs

Ceph, along with OpenStack Swift and Amazon S3, are object-store systems where data is stored as binary objects. However, using terasort, there is a huge perf impact using glusterfs. Ymmv. Thanks for your feedback Replication: In Ceph Storage, all data that gets stored is automatically replicated from one node to multiple other nodes.

HDFS supports a traditional hierarchical file organization. In computing, a distributed file system (DFS) or network file system is any file system that allows access to files from multiple hosts sharing via a computer network.This makes it possible for multiple users on multiple machines to share files and storage resources. The point is that you get rid of the NameNode problem entirely by simply switching to GlusterFS. A single, open, and unified platform: block, object, and file storage combined into one platform, including the most recent addition of CephFS. 14/02/27 15:17:06 WARN conf.Configuration: mapreduce.outputformat.class is deprecated.
