Subject [jira] [Commented] (HIVE-9298) Support reading alternate timestamp formats
Date Tue, 20 Jan 2015 22:57:35 GMT

Jason Dere commented on HIVE-9298:
----------------------------------

I don't think these failures are related to the patch. groupby_grouping_window.q and TestMTQueries
have already been failing in other precommit tests, and I cannot reproduce the failure in
udaf_histogram_numeric.q on either Mac or Linux.

> 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.
