Yuki Morishita commented on CASSANDRA-8735:
-------------------------------------------
Pinging [~blambov] and [~iamaleksey].
As Daniel pointed above, CASSANDRA-7237 removed randomizing part in 3.0+
(https://github.com/apache/cassandra/commit/762db474273f764b189d3613fce33943cd64701b#diff-642bb5d5ca328b50d59f2a550c94e5edR533).
I cannot tell it was intentional or not, so can you take a look and see if it
still need to be patched by this? Thanks.
