James Taylor commented on PHOENIX-1688:
---------------------------------------

That code as removed to fix PHOENIX-1257 (which I asked specifically for you to 
review and you did). The same +1 is done, but in a different way - please 
review the commit for that fix. We may need to do something different 
specifically for sequences.

> dropSequence uses HConstants.LATEST_TIMESTAMP as the Append timestamp

> system.sequence isn't running on the same region server of system.catalog. 
> When the Append uses HContants.LATEST_TIMESTAMP, the append will use the 
> current server time of the RS which is hosting system.sequence table.
> If the two servers have time clock skew, then unexpected errors like 
> SequenceNotFoundException will happen.
