Hi guys, We decided to replace one broker(id=29) in our Kafka cluster. default.replication.factor: 3 num.partitions: 3 So, we moved all topics from brokers 29,30,31 to 30,31 using kafka-reassign-partitions. Everything was ok After replication was done we added replaced node(id=32) and moved all topics to brokers 30,31,32 But we see that all partitions have the same leader is 30: ./kafka-topics --topic=Shop --describe --zookeeper=localhost:2181 Topic:Shop PartitionCount:3 ReplicationFactor:3 Configs: Topic: Shop Partition: 0 Leader: 30 Replicas: 30,32,31 Isr: 31,30,32 Topic: Shop Partition: 1 Leader: 30 Replicas: 32,31,30 Isr: 30,31,32 Topic: Shop Partition: 2 Leader: 30 Replicas: 31,30,32 Isr: 30,31,32 How should we change it? Thanks

Hi guys, Are there any issues to update Cloudera Manager from 5.5.3 to 5.9.0 if we use only Kafka 0.8 with Zookeeper? Can we update directly or we should update to 5.6, then to 5.7, then to 5.8 and finally to 5.9? Thanks

Hi, Alina Seconds are taken into unix times, not miliseconds. So, select unix_timestamp('2014-10-07 00:00:00.999','yyyy-MM-dd HH:mm:ss.SSS') = unix_timestamp('2014-10-07 00:00:00.100','yyyy-MM-dd HH:mm:ss.SSS') Result: True You can check it here http://www.onlineconversion.com/unix_time.htm FYI http://en.wikipedia.org/wiki/Unix_time

I guess you mean Impala. Impala: select unix_timestamp() result: 1 Hive: select unix_timestamp() result: 1421835925
