Some times during a rolling restart, I see lots of these messages during the restart (these happened in the logs of the 2nd server in the cluster to restart (broker 11), after having restarted started, and during the time the 3rd node (broker 9) is doing a controlled shutdown before stopping).
Is it creating new topics (it shouldn't have been!). Or is it moving topics around, or what? 2013-11-01 03:25:55,661 INFO [kafka-request-handler-7] admin.AdminUtils$ - Topic creation { "partitions":{ "0":[ 9, 11 ] }, "version":1 } 2013-11-01 03:26:01,577 INFO [kafka-request-handler-0] admin.AdminUtils$ - Topic creation { "partitions":{ "0":[ 9, 10 ] }, "version":1 } 2013-11-01 03:26:07,767 INFO [kafka-request-handler-1] admin.AdminUtils$ - Topic creation { "partitions":{ "0":[ 9, 11 ] }, "version":1 } 2013-11-01 03:26:07,823 INFO [kafka-request-handler-1] admin.AdminUtils$ - Topic creation { "partitions":{ "0":[ 10, 11 ] }, "version":1 } 2013-11-01 03:26:11,183 INFO [kafka-request-handler-2] admin.AdminUtils$ - Topic creation { "partitions":{ "0":[ 10, 11 ] }, "version":1 } 20
