Sqoop Export from hive with duplicate column name
I am trying to export data from Hive table to Oracle by using sqoop.
My problem is, i have many columns with same name but different values.So in oracle table these columns are treated as different column.I am using hive command line interface.
hive -e "select * from table" > sqoop_hive.txt
sqoop export --connect jdbc:oracle:thin:@jdbc.url /user/db/table/ sqoop_oracle.txt
This will give me error
Error: Error while loading meta row with table: db.table: java.lang.StringIndexOutOfBoundsException: String index out of range: 0
I tried to use
sqoop export --connect
