-------------------------------
Summary: Sqoop unable to export Time data "13:14:12.1234" into
Time colum in RMDBS

Project: Sqoop
Issue Type: Bug
Components: tools
Affects Versions: 1.4.6
Reporter: Eric Lin
Priority: Minor
To re-produce:
Set up MySQL database with following schema:
{code}
CREATE TABLE `test` (
`a` time(2) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1
{code}
Store the following data in HDFS:
{code}
16:56:53.0999
16:56:54.1
16:56:53.0000
16:56:54.1230
{code}
run Sqoop export command to copy data from HDFS into MySQL:
{code}
qoop export --connect jdbc:mysql://<mysql-host>/test --username root --password
password --table test -m 1 --driver com.mysql.jdbc.Driver --export-dir
/tmp/test
{code}
Command will fail with the following error:
{code}

Looks like Sqoop uses java.sql.Time.valueOf function to convert "16:56:53.0999"
to Time object, however, this function only accepts Time in "hh:mm:ss" format:
