Veena Basavaraj updated SQOOP-1720:
-----------------------------------
Description:
It is unclear today as to what is the optimal place where the type mappings
described in the SQOOP-515 between the From and To can happen.
For example in case of HIVE, if the IDF FixedPoint size attribute is given, the
destination schema column type might be dependent on the value of this size is
in the corresponding From schema.
For example in Hive.
Default: bigint
if size < 1 then tinyint
if size < 2 then smallint
if size < 4 then int

To summarize the question s how does the ToInitializer get access to the schema
from the "FROM"
