Wade Simmons commented on CASSANDRA-8616:
-----------------------------------------

I am seeing what appears to be the same issue in 1.2.16. Using sstable2json is trying to open
the commitlog files for writing:

$ sstable2json <sstable-Data.db>
Exception in thread "COMMIT-LOG-ALLOCATOR" FSWriteError in /var/lib/cassandra/commitlog/CommitLog-2-1423079861481.log

> There was a report of sstable2json causing commitlog segments to be written out when
run.  I haven't attempted to reproduce this yet, so that's all I know for now.  Since sstable2json
loads the conf and schema, I'm thinking that it may inadvertently be triggering the commitlog
code.
