The project was aimed to setup a spark cluster with HDFS and run SparkSQL queries (geo-spatial) on the it.

• Native spark cluster was used as cluster manager.
• Hadoop Distributed File System (HDFS) was used as distributed storage system.
• The setup was done using Amazon EC2 virtual machines as nodes.
• Spatial queries such as range query, range join query, distance query, distance join query, hot zone analysis and hot cell analysis were executed.
  • Spatial queries were executed by implementing user defined functions such as ST_contains and ST_within in Scala.
  • ST_contains takes a point and a rectangle and returns a boolean indicating whether the point is inside the rectangle.
  • ST_within takes two points and a distance and returns a boolean indication whether the distance between the points is not more than the distance provided.

Technology used: Apache Spark, Hadoop Distributed File System (HDFS), Scala, sbt build tool, Amazon EC2
