Subject When to use HCatReader/HCatWriter API ?
Date Mon, 03 Dec 2012 06:15:54 GMT
Dear All,

I’m trying to use HCatalog 0.4.0.

In the javadoc, I've found the HCatReader/HCatWriter API and the online
documentation, too (following url).
http://docs.hortonworks.com/HCatalog/CURRENT/readerwriter.html

I’ve read the documentation, but not figured out the usage scene of this
API…

Does anyone know what’s the purpose of this API ?
When to use this API instead of HDFS API or “hadoop dfs” command?


Regards,
-Takashi
