Description
Found during CI run with agitation.
Got the first two error messages 5 times (assuming in a retry on failure block):

Then, we logged that we failed the consistency check
Consistency check fails, retrying java.lang.RuntimeException: Failed to do close consistency check for tablet c;79d0ab;7870a
In the end, we gave up and closed it anyways.
Tablet closed consistency check has failed for c;79d0ab;7870a giving up and closing
Before all of this happened, we tried to bring this tablet online after a failure on a new tserver. During the minc as part of the recovery process, we failed to get the lease on the .rf_tmp file we tried to create. We failed this a couple of times, but eventually got the tmp file we needed and the recovery process completed and we could bring the tablet online. The difference between the in-memory version and the !METADATA version was this one flushed rfile that we created during this recovery process.
The problem eventually fixed itself because the tablet was migrated to a different server and we just took what was (correctly) in the !METADATA table.
There still is an unknown issue of how we missed the flush RFile in the DatafileManager's copy.
