  • Hadoop: What’s the difference between Pig and Hive?

    I'm pretty new to the Hadoop world (been using it for about a month) and I've started to get into Hive, Pig and Hadoop using Cloudera's Hadoop VM. Is there a difference between Pig and Hive? I understand they have similar commands so I'm trying to figure out the big differences.
