Amit Singh Chowdhery created CASSANDRA-8479:
-----------------------------------------------

             Summary: Timeout Exception on Node Failure in Remote Data Center
                 Key: CASSANDRA-8479
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8479
             Project: Cassandra
          Issue Type: Bug
          Components: API, Core, Tools
         Environment: Unix, Cassandra 2.0.11
            Reporter: Amit Singh Chowdhery
            Priority: Minor
             Fix For: 2.0.3


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
