Hyunsik Choi updated TAJO-1185:
-------------------------------
Labels: timezone (was: )
> Default timezone should be UTC+0 instead of depending on JVM
> ------------------------------------------------------------
>
> Key: TAJO-1185
> URL: https://issues.apache.org/jira/browse/TAJO-1185
> Project: Tajo
> Issue Type: Bug
> Reporter: Hyunsik Choi
> Labels: timezone
> Fix For: 0.9.1
>
>
> *Background*
> Currently, Tajo allows users to set a single global timezone. Since the
> initial design, the default timezone of a Tajo cluster depends on the JVM
> timezone if there is no given timezone.
> *Problem*
> BTW, some of cluster nodes probably can have different timezones due to
> missed or wrong setting, which actually is usual in practice. It is like to
> cause wrong results because each task reads and processes a fragment of a
> single table generated with a single timezone.
> *Solution*
> In my opinion, the solution is to force Tajo to use an specified timezone
> instead of depending on JVM timezone. If there is no given timezone, GMT
> should be used in Tajo cluster.
