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

I agree with John, if patched into 1.4 need to handle  backwards compatability 
in some way.  For example if someone is running a 1.4.1 client against a 1.4.3 
server with this bug fix.  May not be as much of an issue for 1.5, since a 1.4 
client and 1.5 server probably will not talk to each other.

> 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)}}.
