> Issue Faced :
> 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~).
> Reference :
> Already a ticket has been opened/resolved and link is provided below :
> https://issues.apache.org/jira/browse/CASSANDRA-8352
> Activity Done as per Resolution Provided :
> Upgraded to Cassandra 2.0.11 .
> We have two 3 node clusters in two different DCs and if one or more of the nodes go down
in one Data Center , ~5-10% traffic failure is observed on the other.
> CL: LOCAL_QUORUM
> RF=3
