The last line in the log before the error was 

INFO [main] 2010-10-01 11:18:06,654 SSTableReader.java (line 162) Sampling index for /local1/junkbox/cassandra/data/system/HintsColumnFamily-tmp-e-87-<>

There were several tmp files for the HintColumnFamily there. I moved them and it started. 

I did run a nodetool drain before killing the node.
