Ergin Demirel commented on OOZIE-1805:
--------------------------------------
Does Oozie respect day light saving with CRON expression. If I adjust my CRON
expression to use UTC time, I don't think it will work when the DST changes in
effect. Is that right?
> Oozie Cron diverges from standard timezone and day behaviours

> Key: OOZIE-1805
> URL: https://issues.apache.org/jira/browse/OOZIE-1805
> Project: Oozie
> Issue Type: New Feature
> Environment: CDH5
> Reporter: Hari Sekhon
>
> The addition of cron syntax in Oozie (OOZIE-1306) is a good idea but the
> implementation of the fields diverges from standard cron which seems counter
> intuitive for unix veterans.
> Taken from Cloudera's blog:
> http://blog.cloudera.com/blog/2014/04/how-to-use-cron-like-scheduling-in-apache-oozie
> 1. Executing in UTC seems like a bad idea when cron uses local time… if you
> wanted to use UTC you would do it for everything and set your servers to UTC
> timezone.
> Having to translate timezones to figure out what to enter requires more
> effort on the part of the user.
> 2. The day field offsets are wrong/needlessly different compared to ISC cron
> which is zero indexed and uses 0 or 7 for Sunday instead of starting from 1.
> These points will cause a less intuitive experience and surely some
> misconfigurations... could we realign this or would it require an upstream
> fix to the Quartz Scheduler? If the latter would it be easier to just reindex
> the days and calculate the timezone in Oozie before feeding to Quartz?
> Thanks
