Example 3 with Message

use of org.apache.cassandra.net.Message in project eiger by wlloyd.

    // hence reasonable to let the coordinator timeout in the very
    // unlikely case we arrive here
    } catch (TimeoutException e) {
    // The coordinator node will have timeout itself so we let that goes
    } catch (IOException e) {
