found a tip:
If you go to windwos -> preferences -> Talend -> Specific Settings -> MetaData of TalendType
you can see how the types are represented.
you can edit the mapping_hive.xml and add a line (top)
<dbType type="DATE" ignoreLen="true" ignorePre="true"/>
and a line (bottom)
<dbType type="DATE">
<talendType type="id_Date" default="true"/>
</dbType>
and get the Date format in hive.
