Dear community, I updated my kafka cluster from version 1.1.0 to 2.0.0 according to the upgrade guide for rolling upgrades today. I encountered a problem after starting the new broker version. The log is full of "Found a corrupted index file corresponding to log file /data/kafka-logs/resultGatewayDataDispatcher-22/00000000000002858226.log due to Corrupt time index found, time index file (/data/kafka-logs/resultGatewayDataDispatcher-22/00000000000002858226.timeindex) has non-zero size but the last timestamp is 0 which is less than the first timestamp 1538583935827}, recovering segment and rebuilding index files... (kafka.log.Log)"
Said recovering takes quite a bit of time. Now I'm not too keen to do the broker update in the production environment because of the relative long processing pause. The questions are: 1.) Is there a way to avoid this error and therefore make starting the new broker faster? 2.) Does the error imply any data loss? Any help is apricated 😊 Best, Claudia
