Centralizing HCatalog metadata
If you often need to use a table from HCatalog, a table and storage management layer for Hadoop, then you may want to centralize the connection information to a given HCatalog and the table schema details in the Metadata folder in the Repository tree view.
Prerequisites:
-
Launch the HortonWorks Hadoop distribution you need to use and ensure that you have the proper access permission to that distribution and its HCatalog.
-
Create the connection to that Hadoop distribution from the Hadoop cluster node. For further information, see Centralizing a Hadoop connection.
