In this example, use a Standard Job to write data to HDFS.
Procedure
In the Studio, create an empty Standard Job.
In a Standard Job, add a tRowGenerator component to
generate random data or add a component to read a file saved in your EC2
instance.
Drag the HDFS metadata from the Repository to the design
space and select tHDFSOutput.
In the Component view of this component, enter the
directory where you want to write your data on HDFS.
Press F6 to run the Job.
If you need to read data from HDFS, you can also drag the HDFS metadata from
the Repository to the design space and select
tHDFSInput. Once again, you will have to specify the path
to the file to be read. You must also provide the schema of this. Once done, you
can right-click the tHDFSInput component and click
Data viewer to have a preview of the content of the
file.
