Sqoop non sa come mappare il tipo di dati BLOB in Oracle in Hive. Quindi devi specificare --map-column-hive COLUMN_BLOB=binary
sqoop import --connect 'jdbc:oracle:thin:@host' --username $USER --password $Password --table $TABLE --hive-import --hive-table $HiveTable --map-column-hive COL_BLOB=binary --delete-target-dir --target-dir $TargetDir -m 1 -verbose
