Soam’s talk “Making Big Data Portable” will get you thinking about the potential pitfalls of moving large quantities of data between Hadoop clusters. Meet with Soam to explore any of the following topics in greater depth:

  • The limitations of using Hadoop’s DistCp to copy data from one cluster to another
  • Ensuring security for in-transit data
  • How to leverage services and tools such as S3 and rsync
  • When to transfer data over networks and when to use disk.
