Hi, In my cluster, one of the nodes went down (due to a hardware failure). We managed to get it fixed in couple of days. But it seems its harder to bring this same node back into cluster without creating read misses. Here is what I did.
Method 1: I copied the data from all the nodes in that data center, into the repaired node, and brought it back up. But because of the rate of updates happening, the read misses started going up. Method 2: I issued a removetoken command for that node's token and let the cluster stream the data into relevant nodes. At the end of this process, the dead node was not showing up in the ring output. Then I brought the node back up. I was expecting, Cassandra to first stream data into the new node (which happens to be the dead node which was in the cluster earlier) and once its done then make it serve reads. But, in the server log, I can see as soon the node comes up, it started serving reads, creating a large number of read misses. So the question is, what is the best way to bring back a dead node (once its hardware issues are fixed) without impacting read misses? Thanks, Eran Chinthaka Withana
