You can convert data in an extract file into comma-separated
value (CSV) format for use with Hadoop Distributed File Systems (HDFS).
- Expand a folder in the Directory Explorer that contains
the convert service, expand the Convert Services node,
and double-click the convert service to edit. The
Convert Service Editor opens.
- Select the Target File Options tab.
- In the Target file format list,
select Hadoop Distributed File System (HDFS).
- In the Target file name field, enter
a name of the target file, which will be used for tables that do not
have a target files specified. Select Use file macro to
enter Optim™ file macros that
dynamically create unique target file names for each table.
- Use the Object Files tab to enter
target file names for the converted tables if a macro is not used
or to override the macro. The grid is populated with table names in
the associated table map.
The following guidelines apply
to files generated for a specific table:
- If you do not specify a file name, the service will create a file
with the name specified in the Target file name for
the service.
- If you do not specify a fully-qualified path for the file, the
converted file will use the same location as the Target
file name for the service.
- Use the HDFS Options tab to define
formatting options for the HDFS CSV files.
- Use the Actions tab to specify a
utility to perform additional processing associated with a convert
service action.
- Save the convert service.
