stack commented on HBASE-4616:
------------------------------

Yeah, what Zhihong said (Thanks Ted).

One thought I had Alex was that we could narrow scope of this patch by not 
trying to hash table name to give it uniform length as part of this patch.  
Instead, just do removal of getClosestOrBefore first (to do this you'll need to 
swap start for end row).  Hows that sound?   For your last-region-in-table 
trick, you have a DELIMITER of ',' currently.   Perhaps the last region has a 
';', which sorts after ',' and is illegal as a tablename character (The 
comparators would have to look for ',' AND ';' to find the table/row boundary).
