Apache Spark is a powerful open source processing engine built around speed, ease of use, and sophisticated analytics. Benefits of Spark includes Speed, Ease of access and being a unified Engine Spark comes packaged with higher-level libraries, including support for SQL queries, streaming data, machine learning and graph processing. If you have large amounts of data that requires low latency processing that a typical MapReduce program cannot provide, Spark is the way to go.

1. Fast processing – The most important feature of Apache Spark that has made the big data world choose this technology over others is its speed. Big data is characterized by volume, variety, velocity, and veracity which needs to be processed at a higher speed. Spark contains Resilient Distributed Dataset (RDD) which saves time in reading and writing operations, allowing it to run almost ten to one hundred times faster than Hadoop.
2. Flexibility – Apache Spark supports multiple languages and allows the developers to write applications in Java, Scala, R, or Python.
3. In-memory computing – Spark stores the data in the RAM of servers which allows quick access and in turn accelerates the speed of analytics.
4. Real-time processing – Spark is able to process real-time streaming data. Unlike MapReduce which processes only stored data, Spark is able to process real-time data and is, therefore, able to produce instant outcomes.
5. Integration – Integrates well with the Hadoop ecosystem and data sources (HDFS, Amazon S3, Hive, HBase, Cassandra, etc.)
6. Better analytics – In contrast to MapReduce that includes Map and Reduce functions, Spark includes much more than that. Apache Spark consists of a rich set of SQL queries, machine learning algorithms, complex analytics, etc. With all these functionalities, analytics can be performed in a better fashion with the help of Spark.

Spark is a plug and play processing engine which helps to process data within Hadoop or Cloud AWS S3 or Azure Blob.
There is no prerequisite as such to learn Spark or Big Data. Though basic understanding of a programming language like . Python, Java, Spark etc will help.
Along with it hardworking in nature ,eagerness to learn and interest in Big Data and Data handling.
Yes Off course you can do transition from any fields and any experience level the only thing is required consistency and practice
Also you need to be more interactive in class and have to study more if you are transitioning from other backgrounds.
