• Type: Bug
• Status: Patch Available
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 1.4.6, 1.4.7
• Component/s: tools

Description

To re-produce:

Set up MySQL database with following schema:

CREATE TABLE `test` (
  `a` time(2) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1

Store the following data in HDFS:

16:56:53.0999
16:56:54.1
16:56:53.0000
16:56:54.1230

run Sqoop export command to copy data from HDFS into MySQL:

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

Command will fail with the following error:

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:
