Am getting exception when using a datetime field in the dynamic index

val conf = Map("es.resource" -> "report-{@creation:YYYY-MM}/users", "es.mapping.id" -> "userId")

users.saveToEs(conf)

where creation field = 2016-03-01 16:52:52.933

16/03/17 14:08:02 WARN TaskSetManager: Lost task 5.0 in stage 0.0 (TID 5, localhost): java.lang.IllegalArgumentException: 2016-03-01 16:52:52.933

Any idea ?

The date is not ISO 8601 format and thus is invalid and cannot be properly parsed.
