Subject [jira] [Commented] (ACCUMULO-776) TimestampFilter should serialize start and end as longs in the IteratorSetting
Date Mon, 05 Nov 2012 21:06:12 GMT

Keith Turner commented on ACCUMULO-776:
---------------------------------------

bq. Well, regardless of version you need backwards compatibility. We don't want things from
suddenly break for users because they upgraded and were using a TimestampFilter as a configured
iterator.

Oh right, I totally spaced on that.  I was only thinking of using it as scan time iterator,
because that the only way I have used it.

> 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)}}.
