> This requires that we have dropped columns in the source table and sstables 
> exist from the "old schema" time.
> This can be very easily reproduced. I used following script:
> {code:java}
> KS=test
> SRCTABLE=bug3_source
> DESTTABLE=bug3_dest
> DATADIR=/usr/local/var/lib/cassandra/data
> TMPDIR=/tmp
> cqlsh -e "CREATE TABLE $KS.$SRCTABLE(a int primary key, b int, c int, d int);"
> cqlsh -e "CREATE TABLE $KS.$DESTTABLE(a int primary key, b int, c int);"
> cqlsh -e "INSERT INTO $KS.$SRCTABLE(a,b,c,d) values(1,2,3,4);"
> nodetool flush $KS $SRCTABLE
> cqlsh -e "ALTER TABLE $KS.$SRCTABLE DROP d;"
> nodetool flush $KS $SRCTABLE
> mkdir -p $TMPDIR/$KS/$DESTTABLE-acdc
> cp $DATADIR/$KS/$SRCTABLE-*/* $TMPDIR/$KS/$DESTTABLE-acdc
> sstableloader -d 127.0.0.1 $TMPDIR/$KS/$DESTTABLE-acdc{code}
