Sean Owen resolved SPARK-6385.
------------------------------
Resolution: Duplicate
> ISO 8601 timestamp parsing does not support arbitrary precision second
> fractions
> --------------------------------------------------------------------------------
>
> Key: SPARK-6385
> URL: https://issues.apache.org/jira/browse/SPARK-6385
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.2.1
> Reporter: Nick Bruun
> Priority: Minor
>
> The ISO 8601 timestamp parsing implemented as a resolution to SPARK-4149 does
> not support arbitrary precision fractions of seconds, only millisecond
> precision. Parsing {{2015-02-02T00:00:07.900GMT-00:00}} will succeed, while
> {{2015-02-02T00:00:07.9000GMT-00:00}} will fail.
> The issue is caused by the fixed precision of the parsed format in
> [DataTypeConversions.scala#L66|https://github.com/apache/spark/blob/84acd08e0886aa23195f35837c15c09aa7804aff/sql/catalyst/src/main/scala/org/apache/spark/sql/types/DataTypeConversions.scala#L66].
> I'm willing to implement a fix, but pointers on the direction would be
> appreciated.
