Subject [jira] [Created] (HBASE-3880) Make mapper function in ImportTSV plug-able
Date Thu, 12 May 2011 15:28:47 GMT
Make mapper function in ImportTSV plug-able

                 Key: HBASE-3880
                 URL: https://issues.apache.org/jira/browse/HBASE-3880
             Project: HBase
          Issue Type: New Feature
            Reporter: Bill Graham

It would be really useful to allow the ability to specify a different Mapper for the {{ImportTsv}}
class to use than the current {{TsvImporter}}. This would allow transformations to be made
on the input data before being added to HBase. One suggestion is to add a new command line
option to specify a user defined mapper (UDM?). Or maybe instead we just refactor it to be
extended where a subclass can specify a new mapper.

The mapper is statically defined and bound to the job though, so I'm not sure of the best
way to make it dynamically plug-able. Suggestions welcome.
