Thanks, Johnny
Actually, they were running .. it went through a series of read and writes
.. and recovered after the error.
Is there any settings I can specify in preparing the Session at java client
driver level, here are my current settings -
PoolingOptions poolingOptions = new PoolingOptions()
.setConnectionsPerHost(HostDistance.LOCAL, 20, 20)
.setMaxRequestsPerConnection(HostDistance.LOCAL, 128)
.setNewConnectionThreshold(HostDistance.LOCAL, 100);
Cluster.Builder builder = Cluster.builder()
.addContactPoints(cp)
.withPoolingOptions(poolingOptions)
.withProtocolVersion(ProtocolVersion.NEWEST_SUPPORTED)
.withPort(port);
