Yes, I have checked. But I thought there was some automatic way of sqoop doing that (without users have to explicitly perform the import for each particular table/column).
I thought Sqoop could transform relational schemas into hbase "schemas", i.e., to get a mapping from one structure to another. But this is not the case right? Thanks.
