Open Studio for Big Data

If you often need to use a database table from HBase, then you may want to centralize the connection information to the HBase database and the table schema details in the Metadata folder in the Repository tree view.

Even though you can still do this from the DB connection mode, using the Hadoop cluster node is the alternative that makes better use of the centralized connection properties for a given Hadoop distribution.

Prerequisites:

  • Launch the Hadoop distribution you need to use and ensure that you have the proper access permission to that distribution and its HBase.

  • Create the connection to that Hadoop distribution from the Hadoop cluster node. For further information, see Centralizing a Hadoop connection.
