This includes: - - * Providing a shared schema and data type mechanism. - * Providing a table abstraction so that users need not be concerned with where - or how their data is stored. - * Providing interoperability across data processing tools such as Pig, Map - Reduce, Streaming, and Hive. - -Data processors using Apache Hadoop have a common need for table management -services. The goal of this table management service is to track data that exists in -a Hadoop grid and present that data to users in a tabular format. HCatalog -provides a single input and output format to users so that individual users need -not be concerned with the storage formats that are chosen for particular data -sets. Data is described by a schema and shares a datatype system. - -Users are free to choose the best tools for their use cases. The Hadoop project -includes Map Reduce, Streaming, Pig, and Hive, and additional tools exist such -as Cascading. Each of these tools has users who prefer it, and there are use -cases best addressed by each of these tools. Two users on the same grid who -share data are not constrained to use the same tool but with HCatalog are free -to choose the best tool for their use case. HCatalog presents data in the same -way to all of the tools, providing interfaces to each of them. - -For the latest information about HCatalog, please visit our website at: - - http://incubator.apache.org/hcatalog - -and our wiki, at: - - https://cwiki.apache.org/confluence/display/HCATALOG - -
