Subject [jira] [Commented] (SPARK-16216) CSV data source does not write date and timestamp correctly
Date Fri, 21 Oct 2016 18:12:59 GMT

    [ https://issues.apache.org/jira/browse/SPARK-16216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15595892#comment-15595892

Reynold Xin commented on SPARK-16216:
-------------------------------------

[~barrybecker4] Hey Berry - can you try setting timestampFormat? The problem was that in the
past we were overloading dateFormat to support both date and timestamp.

>          Components: SQL
>    Affects Versions: 2.0.0

> Currently, CSV data source write {{DateType}} and {{TimestampType}} as below:
> {code}
> +----------------+
> |            date|
> +----------------+
> |1440637200000000|
> |1414459800000000|
> |1454040000000000|
> +----------------+
> {code}
> It would be nicer if it write dates and timestamps as a formatted string just like JSON
data sources.
> Also, CSV data source currently supports {{dateFormat}} option to read dates and timestamps
in a custom format. It might be better if this option can be applied in writing as well.
