Hi Readers,
I am trying to experiment with an MR implementation of HCatalog. There was
an example I found at
http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/latest/CDH4-Installation-Guide/cdh4ig_topic_19_6.htmlthat
i started out from.
I see that the we set the Input Format Class as under.
// An HCatalog record as input
Job job = new Job(conf, "UseHCat");
job.setInputFormatClass(HCatInputFormat.class);
Now this example is based on the new API of MR but I to use Old API, is
there any way of setting the Input Format Class with old API ?
...
