Hadoop and hbase

Hi guys : for those of you that use hadoop --- do you manage your data directly ? Or do you just dump it all in hbase ?

- In general most people I hear of using hadoop are doing it to store millions or billions of records for map/reduce
- The Hadoop m/r api can directly read/write to hbase tables.
- It seems like storing results of m/r jobs in programatically created folders, rather than in a single, machine-managed map (like hbase) is an errand which might be prone to errors in subsequent read and data cleaning stages which might occur.
 
It is sorta covered in the JavaRanch Style Guide.
