Hello, hope you are doing well, We have noticed that the last offset for some of the partitions for topic *__consumer_offsets is zero*. For instance, the following is a testing cluster running version 2.2, this cluster has been running for about 15 months already:
*./bin/kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list localhost:9092 -time -1 --topic __consumer_offsets* *__consumer_offsets:0:0* *__consumer_offsets:1:0* *__consumer_offsets:2:0* *__consumer_offsets:3:0* *__consumer_offsets:4:0* *__consumer_offsets:5:105442* *__consumer_offsets:6:1360081* *__consumer_offsets:7:0* *__consumer_offsets:8:214* *__consumer_offsets:9:0* *__consumer_offsets:10:1235* *__consumer_offsets:11:0* *__consumer_offsets:12:3* *__consumer_offsets:13:336* *__consumer_offsets:14:53858848* *__consumer_offsets:15:0* *__consumer_offsets:16:0* *__consumer_offsets:17:482* *__consumer_offsets:18:4660003* *__consumer_offsets:19:236* *__consumer_offsets:20:227* *__consumer_offsets:21:0* *__consumer_offsets:22:273* *__consumer_offsets:23:3* *__consumer_offsets:24:0* *__consumer_offsets:25:148363133* *__consumer_offsets:26:0* *__consumer_offsets:27:103* *__consumer_offsets:28:7* *__consumer_offsets:29:0* *__consumer_offsets:30:3* *__consumer_offsets:31:0* *__consumer_offsets:32:0* *__consumer_offsets:33:134* *__consumer_offsets:34:95* *__consumer_offsets:35:0* *__consumer_offsets:36:0* *__consumer_offsets:37:550* *__consumer_offsets:38:0* *__consumer_offsets:39:0* *__consumer_offsets:40:1* *__consumer_offsets:41:85* *__consumer_offsets:42:0* *__consumer_offsets:43:0* *__consumer_offsets:44:6* *__consumer_offsets:45:0* *__consumer_offsets:46:0* *__consumer_offsets:47:65069112* *__consumer_offsets:48:930655* *__consumer_offsets:49:108* As you can see, is common to get partitions with the last offset *as zero*, is that expected or normal? am wondering also because, the default partitions number for this *topic is 50*, so, I will assume that by design all of them should be used. What am missing? Cheers! -- Santilli Jonathan
