Getting Started with Apache Drill and MongoDB

Not a lot of people have heard of Apache Drill. That is because Drill caters to very specific use cases, it's very niche. But when used, it can make significant differences to the way you interact with data. First, let's see what Apache Drill is, and then how we can connect our MongoDB data source to Drill and easily query data. What is Apache Drill? According to their website, Apache Drill is "Schema-free SQL Query Engine for Hadoop, NoSQL and Cloud Storage." That's pretty much self-explanatory. So, Drill is a tool to query Hadoop, MongoDB, and other NoSQL databases. You can write simple SQL queries that run on the data stored in other databases, and you get the result in a row-column format. The

Connect Apache Spark to your HBase database (Spark-HBase Connector)

There will be times when you’ll need the data in your HBase database to be brought into Apache Spark for processing. Usually, you’ll query the database, get the data in whatever format you fancy, and then load that into Spark, maybe using the `parallelize()`function. This works, just fine. But depending on the size of the data, this could cause delays. At least it did for our application. So after some research, we stumbled upon a Spark-HBase connector in Hortonworks repository. Now, what is this connector and why should you be considering this? The Spark-HBase Connector (shc-core) The SHC is a tool provided by Hortonworks to connect your HBase database to Apache Spark so that you can tell your Spark context to pickup the
