RxFileSystem: RevoScaleR File System object generator

  • Raksts

Description

This is the main generator for RxFileSystem S3 classes.

Usage

    RxFileSystem( fileSystem, ...)

     ## S3 method for class `RxFileSystem':
print  ( x, ... )

Arguments

fileSystem

character string specifying class name or file system type existing RxFileSystem object. Choices include: "RxNativeFileSystem" or "native", or "RxHdfsFileSystem" or "hdfs". Optional arguments hostName and port may be specified for HDFS file systems.

x

an RxFileSystem object.

...

other arguments are passed to the underlying function.

Details

This is a wrapper to specific generator functions for the RevoScaleR file system classes. For example, the RxHdfsFileSystem class uses function RxHdfsFileSystem as a generator. Therefore either RxHdfsFileSystem() or RxFileSystem("hdfs") will create an RxHdfsFileSystem object.

Value

A type of RxFileSystem file system object. This object may be used in rxSetFileSystem, rxOptions, RxTextData, or RxXdfData to set the file system.

myHdfsFileSystem1 <- RxFileSystem(fileSystem = "hdfs")
rxSetFileSystem(fileSystem = myHdfsFileSystem1 )

# Example 2
myHdfsFileSystem2 <- RxFileSystem(fileSystem = "hdfs", hostName = "myHost", port = 8020)
rxSetFileSystem(fileSystem = myHdfsFileSystem2 )
