The directives Copy
Data to Hadoop, Import a File, and Copy Data from Hadoop enable you
to move data from your files system or database management systems
into and out of Hadoop. The copy directives require database connections
to be defined on the
Databases panel of the
Configuration window.
For more information,
see Set Global Options. The Import a File directive helps you import miscellaneous
files from your file system into Hadoop as columnar tables.
