Subject [jira] [Commented] (HIVE-9298) Support reading alternate timestamp formats
Date Tue, 03 Feb 2015 08:29:34 GMT


Lefty Leverenz commented on HIVE-9298:

Doc note:  timestamp.formats can be documented in the Timestamps section of the Hive Data
Types wikidoc.  (At present we don't have a section on SerDe properties in the wiki, but perhaps
we should.)

* [Hive Data Types -- Timestamps |]
* [SerDe Overview |]

> There are some users who want to be able to parse ISO-8601 timestamps, as well to set
their own custom timestamp formats. We may be able to support this in LazySimpleSerDe through
the use of a SerDe parameter to specify one or more alternative timestamp patterns to use
to parse timestamp values from string.
> If we are doing this it might also be nice to work in support for HIVE-3844, to parse
numeric strings as timestamp by treating the numeric value as millis since Unix epoch. This
can be enabled through the SerDe params as well.
