Kevin Weil updated HADOOP-6115:
-------------------------------
Attachment: HADOOP-6115.patch
This patch adds the ability to specify a "where" clause to sqoop, in the form
<normal sqoop command> --where "my_row > 0 and my_text like '%sqoop%'"
It also works with sqoop's mysql-specific --local flag, using mysqldump's -w
flag.
> Sqoop should allow a "where" clause to avoid having to export entire tables

> Project: Hadoop Common
> Issue Type: Improvement
> Components: contrib/sqoop
> Affects Versions: 0.21.0
> Reporter: Kevin Weil

>
> Sqoop currently only exports at the granularity of a table. This doesn't
> work well on systems with large tables, where the overhead of performing a
> full dump each time is significant. Allowing the user to specify a where
> clause is a relatively simple task which will give Sqoop a lot more
> flexibility.
