Do I need Hadoop to run Spark?
No, but if you run on a cluster, you will need some form of shared file system (for example, NFS mounted at the same path on each node). If you have this type of filesystem, you can just deploy Spark in standalone mode.
Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
