spark_read_json(sc, name, path, options = list(), repartition = 0, memory = TRUE, overwrite = TRUE)
The name to assign to the newly generated table.
The path to the file. Needs to be accessible from the cluster. Supports the "hdfs://", "s3n://" and "file://" protocols.
A list of strings with additional options.

Boolean; should the data be loaded eagerly into memory? (That is, should the table be cached?)

You can read data from HDFS (
hdfs://), S3 (
s3n://), as well as
the local file system (
If you are reading from a secure S3 bucket be sure that the
