Hi there,
Im running a java process on a 4 node cassandra 3.9 cluster on EC2 (instance
type t2.2xlarge), the process running separately on each of the nodes (i.e. 4
running JVMs).
The process is just doing reads from Cassandra and building a SOLR index and
using the java driver with consistency level LOCAL_ONE.
However, the following exception is through:
com.datastax.driver.core.exceptions.TransportException: [/10.0.0.2:9042]
Connection has been closed

at
com.datastax.driver.core.ArrayBackedResultSet$1.hasNext(ArrayBackedResultSet.java:143)
where 10.0.0.2 is not the local machine. So my questions:
- Should this happen when Im using consistency level LOCAL_ONE and just doing
reads ?
- Does this suggest non-local reads are happening ?
Many thanks for any help/ideas.
Frank
