Subject [jira] [Created] (SQOOP-3330) Sqoop --append does not work with -Dmapreduce.output.basename
Date Tue, 29 May 2018 06:38:00 GMT
Eric Lin created SQOOP-3330:
-------------------------------

             Summary: Sqoop --append does not work with -Dmapreduce.output.basename
                 Key: SQOOP-3330
                 URL: https://issues.apache.org/jira/browse/SQOOP-3330
             Project: Sqoop
          Issue Type: Bug
          Components: tools
    Affects Versions: 1.4.7
            Reporter: Eric Lin


When adding --append to Sqoop directory import with -Dmapreduce.output.basename, all files
will be ignored, which end up nothing being imported. See below DEBUG output:

sqoop import -Dmapreduce.output.basename="eric-test" --connect jdbc:mysql://mysql-host.com/test
--username root --password 'root' --table test --target-dir /tmp/ericlin-test/sqoop/test --fields-terminated-by
'\t' --verbose --append

{code}

This is due to AppendUtils only recognizes file name starts with "part.*-([0-9]"
