[~mambocab] We are using cassandra 2.1.12

In production we got a first error doing a repair (-pr -par)

We decided to do another a repair over this token range 8699512854132214411,8702471448538509513
using the next command.

We tried to run again the same repair on the same node with the same tokenrange and it finished
without error

It seems this error comes up by hazard. We notice that our first repair -pr -par has finished
repairing all the tokenranges, but that one we got the error.
