[jira] [Commented] (SQOOP-423) Sqoop import of timestamps to Avro
from Postgres - Timezone Issue
[ https://issues.apache.org/jira/browse/SQOOP-423?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16786487#comment-16786487 ]
yuxiaoyong commented on SQOOP-423:
----------------------------------
We have encountered the same issue, the TIMESTAMP values are 8 hours ahead and our format is textfile !!
Instead of use --table TABLE_NAME ,we use --query " " to avoid the automatically transformation from sqoop, and the TIMESTAMP keeps same as the MYSQL DB.
We don't known why it happens, because java.sql._Timestamp has nothing to do with TIMEZONE. Hope guys to fix this bug_

> Key: SQOOP-423
> URL: https://issues.apache.org/jira/browse/SQOOP-423
> Project: Sqoop
> Issue Type: Bug
> Affects Versions: 1.3.0
> Reporter: Lynn Goh
> Priority: Major
>
> I am running sqoop-1.3.0-cdh3u2 on a Mac and when I sqoop import from a postgres table with columns of type 'timestamp without time zone', they are converted to longs in the time zone of my local operating system, even after I have started Hadoop up with TZ=GMT or passed in HADOOP_OPTS="-Duser.timezone=GMT". My ultimate goal is to sqoop import into long representations that are in GMT timezone rather than my operating system's timezone.
> Postgres example:
> {code}
> acamp_id | start_time | end_time
> ----------+---------------------+---------------------
> 1 | 2008-01-01 00:00:00 | 2011-12-16 00:00:00
> {code}
> After import, you can see the values are 8 hours ahead, even with TZ=GMT and user.timezone set properly (this is the json representation of the parsed imported avro file):
> {code}
> {"acamp_id": 1, "end_time": 1324022400000, "start_time": 1199174400000}
> {code}
> date utility invocation:
> {code}
> lynngoh@unknown:~$ date -u -r 1199174400
> Tue Jan 1 08:00:00 UTC 2008
> {code}
