Hi,

We have following configuration in our project for cassandra. 

Total nodes in Cluster-5

Replication Factor- 3

Consistency- LOCAL_QUORUM

We get the writetimeout exception from cassandra even when 2 nodes are up.

Below is the exception we got:-

com.datastax.driver.core.exceptions.WriteTimeoutException: Cassandra timeout during write query at consistency LOCAL_QUORUM (3 replica were required but only 2 acknowledged the write)
