While it’s easy to get started with MongoDB, more complex issues emerge when you’re building applications. You may find yourself wondering things like:

• How do I re-sync a replica member in replica set?
• How can I recover MongoDB after a crash?
• When should I use MongoDB’s GridFS specification to store and retrieve files?
• How do I fix corrupted data?

This blog post shares a few tips for handling these situations when you’re using MongoDB.

Apache™ Hadoop® is an open source, Java-based framework that’s designed to process huge amounts of data in a distributed computing environment. Doug Cutting and Mike Cafarella developed Hadoop, which was released in 2005.

Built on commodity hardware, Hadoop works on the basic assumption that hardware failures are common. The Hadoop framework addresses these failures.

In Part 1 of this two-part blog series, we’ll cover big data, the Hadoop ecosystem, and some key components of the Hadoop framework.
