HCatalog is a table storage management tool for Hadoop that exposes the tabular data of Hive metastore to other Hadoop applications. It enables users with different data processing tools (Pig, MapReduce) to easily write data onto a grid. HCatalog ensures that users don’t have to worry about where or in what format their data is stored. This is a small tutorial that explains just the basics of HCatalog and how to use it.
