I'm seeing hinted handoff kick in on all our nodes during periods of high activity, but all the nodes seem to be up (according to the logs and nodetool status). The pattern in the logs is something like this:
18:10:45 194 READ messages dropped in last 5000ms 18:11:10 Started hinted handoff for host: 7668c813-41a9-4d42-b362-5420528fefa0 with IP: /10.... 18:11:11 Finished hinted handoff of 13 rows to endpoint /10.... This happens on all the nodes every 10 min, and with a different endpoint each time. tpstats shows thousands of dropped reads, but no other types of messages are dropped. Do slow reads trigger hint storage? If hints are being stored, doesn't that imply DOWN nodes, and why don't I see that in the logs? Dane
