----------------------------------
Summary: Duplicate records found when split-by column is of char(n)
Key: SQOOP-2664
URL: https://issues.apache.org/jira/browse/SQOOP-2664
Project: Sqoop
Issue Type: Bug
Components: sqoop2-jdbc-connector
Affects Versions: 1.4.5
Environment: Hortonworks: 2.2.4.2
Sqoop: 1.4.5
MS SQL: R2008
Reporter: Dhaval Modi
Hi,
While work with SQOOP, we found an issue where records are duplicated while
importing data. This is seen when split-by column is of type char(n).
We understand, ideally, integral columns with not null type must be chosen for
split-by column, but in our case, all integral columns has null values. There
is open bug (SQOOP - 2536) raised for this issue.
But as sqoop have support for char datatype to be used in split-by column, and
it giving unexpected results. Thus raising this bug.
