apache - Setting up a Hadoop Cluster on Amazon Web services with EBS -


i wondering how setup hadoop cluster (say 5 nodes) through aws. know how create cluster on ec2 don't know how face following challenges.

  1. what happens if lose spot instance. how keep cluster going.
  2. i working datasets of size 1tb. possible setup ebs accordingly. how can access hdfs in scenario.

any great!

depending on requirements, these suggestions change. however, assuming 2 master , 3 worker setup, can use r3 instances master nodes memory intensive app optimized , go d2 instances worker nodes. d2 instances have multiple local disks , can withstand disk failures while still keeping data safe.
answer specific questions,

  1. treat hadoop machines linux applications. happen if general centos spot instances lost? hwnce, advised use reserved instances.
  2. hadoop typically stores data maintaining 3 copies , distributing them across worker nodes in forms of 128 or 256 mb blocks. so, have 3tb data store across 3 worker nodes. obviously, have consider overhead while calculating space requirements.
