12. © 2013 Mellanox Technologies 12 The Great Things in Hadoop Distributed File System HDFS is a block storage solution Block size can be modified to provide efficient solutions for very large files Inherent reliability, no need for high end storage solution to make sure data is there! Tuned for Hadoop work loads, write one and read many

13. © 2013 Mellanox Technologies 13 The Less Great Things in HDFS It’s hard to manage the different setting to get the right nodes into the right capabilities. Ingress and extraction of data requires additional tools. Small files or latency sensitiveDefault 3x Replication Metadata Server Failure
