Subject Re: Cleanup and old files
Date Tue, 31 Dec 2013 03:24:09 GMT
I see the SSTable in this log statement:   Stream context metadata (along
with a bunch of other files)....but I do not see it in the list of files
"Opening" (which I see quite a bit of, as expected).

Safe to try moving that file off server (to a backup location)?  If I tried
this, would I want to shut down the node first and monitor startup to see
if it all of a sudden is 'missing' something / throws an error then?
