Here’s how to find out the optimal memory settings for your Hadoop cluster

Mature Relational Database Systems (RDBMSs) are very much self-optimizing. In fact, the capabilities of such a system to determine for itself how to execute the query in the most efficient way is so good that the pinnacle programming language of RDBMSs – the Structured Query Language (SQL) – almost completely focuses on what should be done rather than how it should be done. This is not as true in the world of emerging technology Hadoop. Hadoop demands a little more attention from the Engineers, Scientists and/or Administrators to make it fly. Luckily, there is a tool to help out and it will show you how to find the optimal values for your cluster in minutes!
