> The {{TestReplicatedTabletWritesWithLeaderElection}} of the {{client-test}} is flaky.  Time to time in ASAN build configuration it fails with the following error:
> {noformat}
> I0924 20:26:19.869351 14037 client-test.cc:4304] Counting rows...               
> src/kudu/client/client-test.cc:4308: Failure
>       Expected: 2 * kNumRowsToWrite                                             
>       Which is: 200

>       Which is: 100 
> {noformat}
> It seems there is implicit assumption in the test about fast propagation of Raft transactions to follower replicas.
> I attached the full log of the failed tests scenario.
