Can you use sqoop to retrieve the data directly from the database and dump it into Hive? That will solve your delimiter problem.

I would recommend not using CSV in your case. If you have commas in the fields then you can't really delimit them with commas because, as you have noticed, you will have field breaks in the middle of a field.

 

Can you get the source data exported some other way?

Right and Thank You. What format you suggest?

Where is the data coming from? You could use a binary format like Avro or Parquet if your source system can export that way. If you MUST have a text file with a delimiter, you need a delimiter that is not anywhere in the data.

Have you tried using openSerde In DDL?

Create Table tablename(columns)

ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde';

 

Thanks,
