Summary: Sqoop
Key: SQOOP-1078
URL: https://issues.apache.org/jira/browse/SQOOP-1078
Project: Sqoop
Issue Type: Bug
Components: connectors, connectors/mysql, connectors/postgresql
Affects Versions: 1.4.3, 1.4.2, 1.3.0
Reporter: Tim Howe
Priority: Minor
A problem exists in Sqoop's incremental import, namely that any imports
after the first report success but the data never appears.
A temporary file created on HDFS with the data but is deleted upon
completion rather than being moved into place.
It turns out to be a conflict between the "direct mode" database
managers and "incremental mode" import. Ordinarily Sqoop ends up
creating files named part-m-nnnnn where nnnnn is an incrementing file
partition number. However the direct mode importer creates files of
the form data-nnnnn. This poses a problem because AppendUtils, which
is used to move files into place at the end of a direct import, only
copies files which match that part-m-nnnnn format and discards the
rest.
