Subject [jira] [Commented] (ACCUMULO-776) TimestampFilter should serialize start and end as longs in the IteratorSetting
Date Tue, 06 Nov 2012 02:12:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13491122#comment-13491122

John Vines commented on ACCUMULO-776:
-------------------------------------

Interesting, that's a neat application of the visibilities.

I looked over the patch again, and I'm wondering if we have a compatability issue after all.
I don't think anything is being changed in how things are being stored in ZK. So the only
issue is the wire compatability which Keith mentioned before, which is nowhere as severe of
an issue IMO.

> Although the TimestampFilter supports using longs to set the start or end timestamp,
it formats them as strings using SimpleDateFormat when storing or retrieving them in the IteratorSetting.
> This results in exceptions when the timestamps being used aren't able to be formatted
as _yyyyMMddHHmmssz_. For example, try {{setEnd(253402300800001,true)}}
> Instead, {{setStart()}} and {{setEnd()}} could just as easily use {{String.valueOf(long
i)}} to store the values, and {{init()}} could retrieve them using {{Long.valueOf(String s)}}.
