Running the Largest HDFS Cluster

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

HDFS is a highly scalable fault-tolerant distributed file system designedfor running on low-cost commodity hardware. HDFS creates multiple replicas of data blocks and distributes them on compute nodes throughout a cluster to enable fast computation on large data sets.

Facebook uses HDFS as a data warehouse, storing Hive tables that collect all Facebook user behaviors from the Facebook's front pages. The warehouse HDFS cluster is consisted of more than thousands of nodes, configured with over 100PB of storage space. Currently the cluster stores hundreds million files, with a growth rate of around hundreds TB of physical space each day. Meanwhile the cluster services a huge load of I/O requests.

The Facebook warehouse HDFS cluster by far is the largest HDFS in the world in term of its capacity. Keeping such a huge file system up andrunning quickly and reliably gives exciting and interesting challenges tothe HDFS team. This talk will present more information on the scale of thecluster, the problems we face, and the solutions we come up to improve theavailability, the scale, and the storage efficiency of the cluster.
