I have a 4 node cluster, version 1.1.2, replication factor of 4, read/write consistency of 3, level compaction. Several questions.
1) Should nodetool repair be run regularly to assure it has completed before gc_grace? If it is not run, what are the exposures? 2) If a node goes down, and is brought back up prior to the 1 hour hinted handoff expiration, should repair be run immediately? 3) If the hinted handoff has expired, the plan is to remove the node and start a fresh node in its place. Does this approach cause problems? Thanks
