Review request for Sqoop.


Bugs: SQOOP-3330
    https://issues.apache.org/jira/browse/SQOOP-3330


Repository: sqoop-trunk


Description
-------

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:

{code}
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]"
