Since my last two comments, I increased my RF and started a rolling repair on 
my nodes.  This has caused this NPE to pop up on all the boxes as the process 
SSTables.  Again, all the nodes are fresh 0.8.6 installs from a few days ago 
using the ComboAMI.

Also got the same NPE when doing a repair on a different node. This time, the 
NPE was preceded by a different NPE:

So I restarted the node making the NPE above and ran the decommission again (on 
the other node) and it successfully finished decommissioning.  A few hours 
later I tried to decommission another node and received this error, on a 
separate node from the two mentioned before, which is a new node running 0.8.6 
for just about a day now.

I just got a similar-looking NPE stack trace.  The node that raised the 
exception was receiving streams from a node being decommissioned (with 
nodetool decommission).  Both nodes were running 0.8.6; both had been 
upgraded a few hours earlier from 0.8.4.

Sylvain Lebresne commented on CASSANDRA-2863:
-

I'm a little bit baffled by that one. Trusting the stack trace, apparently when 
SSTW.RowIndexer.close() is called, the iwriter field is null. But iwriter is 
set in prepareIndexing() that is called the line before index() in 
SSTW.Builder. Thus if an exception happens in prepareIndexing, we shouldn't 
arrive to the index() method (which is the one triggering the close()). And 
looking at the use of iwriter, no other line set it (so it can't be set back to 
null after prepareIndexing()).

So I mean we can add a {{if (iwriter != null)}} before calling the close, but 
the truth is I have no clue how it could ever be null at that point.

Héctor: are you positive that you are using stock 0.8.1 ?
