    We have a Geo-red setup with 2 Data centers having 3 nodes each. When we bring down a single Cassandra node down in DC2 by kill -9 <Cassandra-pid>, reads fail on DC1 with TimedOutException for a brief amount of time (15-20 sec~).

This error occurred when we took one node from remote DC down. Our main
concern is the *org.apache.cassandra.thrift*.*TimedOutException* exception
in our application logs. Why read failed when we used LOCAL_QUORUM. Failure
of a node in other DC must not impact our DC if we are using LOCAL_QUORUM.
Second question is Why Rapid Read Protection is not working as expected?

I believe you were attempting to share:
https://issues.apache.org/jira/browse/CASSANDRA-8352

Your cassandra logs outputs the following:

Which indicates that your server is under pressure at that moment and
points you to look at your server logs for further diagnosis.
