Description

While doing some testing around adding/removing nodes under load with cassandra-2.1 head as of a few days ago (after was 2.1.5 tagged) I am seeing stream out errors with file not found exceptions. The file in question just finished being compacted into a new file a few lines earlier in the log. Seems that streaming isn't holding onto Ref's correctly for the stuff in the stream plans.

I also see a "corrupt sstable" exception for the file the "missing" file was compacted to. Trimmed logs with just the compaction/streaming related stuff:
You can see the stream plan is initiated in between the compaction starting, and the compaction finishing.
