Running the hdfs script without any arguments prints the description for all commands. Usage: hdfs [SHELL_OPTIONS] COMMAND [GENERIC_OPTIONS] [COMMAND_OPTIONS] Hadoop has an option parsing framework that employs parsing generic options as well as running classes. However, an extra layer of security in the cloud requires a special toolkit to access the BigInsights service in Bluemix. The HDFS for Bluemix toolkit contains Streams operators that can connect through the Knox Gateway. This article shows how to use these operators to read and write files to HDFS on Bluemix. Hortonworks Data Platform (HDP) 2.3 represents the latest innovation from across the Hadoop ecosystem, especially in the area of security. With HDP 2.3, enterprises can secure their data using a gateway for perimeter security, provide fine grain authorization and auditing for all access patterns, and ensure data encryption over the wire as well as stored on disk.
