RangeTombstoneList.diff AssertionError in 2.1.0

[Philo Yang <ud...@gmail.com>]

Hi,all

after upgrading to 2.1.0, I found there are many exceptions in system.log.
It appears in nodes upgraded from 2.0 as well as in nodes newly added at
2.1.0. When I set the read repair chance to 0.0, it disappears.

ERROR [SharedPool-Worker-8] 2014-09-27 16:44:50,188 ErrorMessage.java:218 -
Unexpected exception during request
