> Sqoop incremental import data from any database to HBase, if source table's column from
a row is updated to NULL, then target HBase table still showing the previous value for that
column. 
> So if you do a scan on the table for that row, HBase shows the previous values of the
column.
> Expected Result: Sqoop incremental import, If NULL columns are there in source, then
HBase need not store that and if it already exists need to delete that column for a given
row.
