I have a few column families that I decided to get rid of the secondary indexes 
on.  I see that there aren't any new index SSTables being created, but all of 
the old ones remain (some from as far back as September).  Is it safe to just 
delete then when the node is offline?  Should I run clean-up or scrub?

Also, when adding a new node to the ring the new node will build indexes for 
the ones that supposedly don't exist any longer.  Is this supposed to happen?  
Would this have happened if I had deleted the old SSTables from the previously 
existing nodes?

The nodes in question have either been upgraded from v0.8.1 => v1.0.2 (scrubbed 
at this time) => v1.0.6 or from v1.0.2 => v1.0.6.  The secondary index was 
dropped when the nodes were version 1.0.6.  The new node added was also 1.0.6.
