Connecting to HDFS
Apache HDFS (Hadoop Distributed File Systems) provides a software framework for distributed storage and processing of big data. In combination with tools such as MapReduce, Yarn, and other core modules, HDFS lets organizations build Apache Hadoop clusters of hundreds or thousands of nodes that can handle datasets of terabyte size. A robust ecosystem of other tools can take advantage of data stored in HDFS.
To connect to HDFS, use the Component tab of the tHDFSExist component. Enter the Hadoop distribution and version, the HDFS directory, and name of the file you want to use.
