sqoop import --connect jdbc:oracle:thin:@host --username --password  --m         


        

Answer 1

Sqoop does not know how to map blob datatype in oracle into Hive. So You need to specify --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
