Same is true if started from 1.2.9 version to 2.0.x Seems like Cassandra-5383 is the related issue.
The code in the function mutateLevel (from 1.2.5 to 1.2.9 and later ) is indirectly using the java file::renameTo function. And that will not work on Windows if the file already exists. Don't know about Linux, but even the java function description is already telling that the behavior of the function can be machine dependent. So even on linux based systems, and even if that functions returns with success, still does not confirm that actually the old file name/content was removed and the new file name/content is used as replacement.

Unfortunately, you must go through 1.2.9 first.

This is due to the code in LeveledManifest:: mutateLevel. The method already has a comment saying that it is scary ... On windows, one cannot use the File::rename if the target file name already exists. Also, even on Linux, I'm not sure if a rename would actually 'overwrite/implicit-delete' the content of the target file. Anyway, adding code (below) before the FileUtils.renameWithConfirm should work in both cases (maybe even rename the fromFile to be able to recover...) File oTo = new File(filename); if ( oTo.exists() ) oTo.delete(); java.lang.RuntimeException: Failed to rename .....xxx\Function-ic-10-Statistics.db-tmp to .....xxx\Function-ic-10-Statistics.db at org.apache.cassandra.io.util.FileUtils.renameWithConfirm(FileUtils.java:136) ~[main/:na] at org.apache.cassandra.io.util.FileUtils.renameWithConfirm(FileUtils.java:125) ~[main/:na] at org.apache.cassandra.db.compaction.LeveledManifest.mutateLevel(LeveledManifest.java:601) ~[main/:na] at org.apache.cassandra.db.compaction.LegacyLeveledManifest.migrateManifests(LegacyLeveledManifest.java:103) ~[main/:na] at org.apache.cassandra.service.CassandraDaemon.setup(CassandraDaemon.java:247) ~[main/:na] at org.apache.cassandra.service.CassandraDaemon.activate(CassandraDaemon.java:443) ~[main/:na] Regards, Ignace Desimpel
