Hi, I'm doing a research paper on Hadoop -- specifically relating to its dependency on HDFS. I need to determine if and how HDFS can be replaced. As I understand it, there are a number of organizations that have produced HDFS alternatives that support the Hadoop ecosystem, i.e. MapReduce, Hive, HBase, etc.
With the "if" part being answered, I'd appreciate insight/guidance on the "how" part. Essentially, where can I find information on what MapReduce and the other Hadoop subprojects require of the underlying file system and how these subprojects expect to interact with the file system. Thanks! Best, Ari
