Anubhav Kale commented on CASSANDRA-10580:
------------------------------------------
My HEAD is indeed pointing to different location:
f1c3df0e848638735c790b4817adf6411a52a064. I pulled down 2.2. via below and then
made changes.
git clone http://git-wip-us.apache.org/repos/asf/cassandra.git cassandra-2.2
I will dig some more on why this did not work correctly.

> In our production cluster, we are seeing a large number of dropped mutations.
> At a minimum, we should print the time the thread took to get scheduled
> thereby dropping the mutation (We should also print the Message / Mutation so
> it helps in figuring out which column family was affected). This will help
> find the right tuning parameter for write_timeout_in_ms.
> The change is small and is in StorageProxy.java and MessagingTask.java. I
> will submit a patch shortly.
