Subject [jira] [Commented] (HIVE-3454) Problem with CAST(BIGINT as TIMESTAMP)
Date Thu, 19 Feb 2015 08:06:13 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3454?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14327096#comment-14327096
] 

Jason Dere commented on HIVE-3454:
----------------------------------

If this config setting is initialized once in a static block, then for hiveserver2 all subsequent
sessions would be stuck with the initial setting regardless of the config settings of the
session, right? During the MR jobs, would we then see the sec/msec behavior flip to use the
session's config settings since the static variable is being initialized for the first time
in MR task?

> Ran into an issue while working with timestamp conversion.
> CAST(unix_timestamp() as TIMESTAMP) should create a timestamp for the current time from
the BIGINT returned by unix_timestamp()
> Instead, however, a 1970-01-16 timestamp is returned.
