Subject Re: units in MDL and HICC

There is a special keyword called conversion.<record_type>.<key>,
By putting 1000, it will apply column_value*1000 before inserting into
database.  I did not test much of this pre chukwa days.  I am not sure if it
stil works.

The right thing to do is to improve the parser to do the right thing hence,
cleansed and unified truth is stored in hdfs.
