Re: [sqoop-user] Sqoop Export : exporting selective columns from a table in HDFS

[Cheolsoo Park <ch...@cloudera.com>]

Hello Rakesh,

Exporting selective columns is not supported at the moment by Sqoop.
("--columns" is an import-specific option.) If you like to have exporting
selective columns in Sqoop , please file a JIRA at:
https://issues.apache.org/jira/browse/SQOOP

Thanks,
Cheolsoo
