Write to Aerospike from spark via MapPartitions Problem Statement : Data from HDFS needs be read from spark and saved in Aerospike. One needs to use mapPartition transformation to achieve the same.

/**@param file a file path * @param the Java type of records to read from the file * @return an Avro reader builder * @deprecated will be removed in 2.0.0; use {@link # You can use AvroParquetReader from parquet-avro library to read a parquet file as a set of AVRO GenericRecord objects. Using Avro to define schema Rather than creating Parquet schema and using ParquetWriter and ParquetReader to write and read file respectively it is more convenient to use a framework like Avro to create schema. Then you can use AvroParquetWriter and AvroParquetReader to write and read Parquet files. Avro implementations for C, C++, C#, Java, PHP, Python, and Ruby can be downloaded from the Apache Avro™ Releases page. This guide uses Avro 1.10.2, the latest version at the time of writing. For the examples in this guide, download avro-1.10.2.jar and avro-tools-1.10.2.jar.
