Sqoop creates splits based on values in a particular column of the table which is specified by –split-by by the user through the import command. If it is not available, the primary key of the input table is used to create the splits.

How do I select a column by split in sqoop?

If you don’t have such a column in your table the only workaround is to use only 1 mapper: “-m 1”. The answer is outdated. It is possible to use a character attribute as split-by attribute. no guarantees though that sqoop splits your records evenly over your mappers though.

How do I specify delimiter in sqoop export?

→ Simple Export: By default data is assumed to be delimited by comma (,) if not specifically specified. → Export from Delimited File: “–input-fields-terminated-by” can be used to specify specific delimiter present in input data file. In the below example, ctrl A is used present as file delimiter.
