Summary: Provide an option automatically choose one mapper when
neither primary key is defined nor split by column is provided
Key: SQOOP-2191
URL: https://issues.apache.org/jira/browse/SQOOP-2191
Project: Sqoop
Issue Type: Bug
Reporter: Venkat Ranganathan
Assignee: Venkat Ranganathan
This is typically an issue when import-all-tables is used on a schema. There
may be tables without any primary key and currently the only option is identify
them and exclude them proactively.
The solution proposed is to add an option to automatically reset the num
mappers to one so that import-all-tables can continue by importing such tables
with one mapper
