Another week, another gem from the Data Science Association. If you're trying to prototype a data analysis algorithm, benchmark performance on a new platform like Spark, or just play around with a new tool, you're going to need reliable sample data. As anyone familiar with testing knows, good data can. There are 2 issues with the dataset. 1. Size – even the subset (10,000 songs) dataset is 1.8 GB what if we want to get 200 MB dataset or a dataset even smaller. 2. Format – The files in the dataset are in HDF5 format. We need to convert the files to tab delimited (or any delimiter) text files to work with Hadoop. Apache Sqoop provides a framework to move data between HDFS and relational databases in a parallel fashion using Hadoop's MR framework. As Hadoop becomes more popular in enterprises, there is a growing need to move data from non-relational sources like mainframe datasets to Hadoop. Deleting the FileSet will also delete this directory and all the files it contains. The Hadoop input and output format. They are given as dataset properties by their class names. When a FileSet is used as the input or output of a MapReduce program, these classes are injected into the Hadoop configuration by the CDAP runtime. How many persons survived – traveling class wise.
