We are seeing a problem that we we try to send messages to new topic it fails kafka.common.LeaderNotAvailableException. But usually this problem will be transient and if we re-send messages to same topic will work. But now we tried rending message to same topic several time, but still fails with same error:
In the server log I see ] Auto creation of topic test-sjl2 with 8 partitions and replication factor 3 is successful!. But listTopics command shows leader "none" like below: topic: test-sjl2 partition: 0 leader: none replicas: 2,4,3 isr: topic: test-sjl2 partition: 1 leader: none replicas: 3,2,4 isr: topic: test-sjl2 partition: 2 leader: none replicas: 4,3,2 isr: topic: test-sjl2 partition: 3 leader: none replicas: 2,3,4 isr: topic: test-sjl2 partition: 4 leader: none replicas: 3,4,2 isr: topic: test-sjl2 partition: 5 leader: none replicas: 4,2,3 isr: topic: test-sjl2 partition: 6 leader: none replicas: 2,4,3 isr: topic: test-sjl2 partition: 7 leader: none replicas: 3,2,4 isr: I also see following NotLeaderForPatritionExcetion and ZookeeperExcetion in logs kafka.common.NotLeaderForPartitionException at sun.reflect.GeneratedConstructorAccessor19.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:513) at java.lang.Class.newInstance0(Class.java:355) at java.lang.Class.newInstance(Class.java:308) at kafka.common.ErrorMapping$.exceptionFor(ErrorMapping.scala:70) at kafka.server.AbstractFetcherThread$$anonfun$processFetchRequest$4$$anonfun$apply$5.apply(AbstractFetcherThread.scala:158) at kafka.server.AbstractFetcherThread$$anonfun$processFetchRequest$4$$anonfun$apply$5.apply(AbstractFetcherThread.scala:158) at kafka.utils.Logging$class.warn(Logging.scala:88) at kafka.utils.ShutdownableThread.warn(ShutdownableThread.scala:23) at kafka.server.AbstractFetcherThread$$anonfun$processFetchRequest$4.apply(AbstractFetcherThread.scala:157) at kafka.server.AbstractFetcherThread$$anonfun$processFetchRequest$4.apply(AbstractFetcherThread.scala:113) at scala.collection.immutable.HashMap$HashMap1.foreach(HashMap.scala:178) at scala.collection.immutable.HashMap$HashTrieMap.foreach(HashMap.scala:347) at kafka.server.AbstractFetcherThread.processFetchRequest(AbstractFetcherThread.scala:113) at kafka.server.AbstractFetcherThread.doWork(AbstractFetcherThread.scala:89) at kafka.utils.ShutdownableThread.run(ShutdownableThread.scala:51) 2013-09-12 23:54:10,838 [kafka-request-handler-2] ERROR (kafka.utils.ZkUtils$) - Conditional update of path /brokers/topics/FunnelProto/partitions/4/state with data { "controller_epoch":3, "isr":[ 2, 5 ], "leader":2, "leader_epoch":2, "version":1 } and expected version 14 failed due to org.apache.zookeeper.KeeperException$BadVersionException: KeeperErrorCode = BadVersion for /brokers/topics/FunnelProto/partitions/4/state 2013-09-12 23:54:10,838 [kafka-request-handler-2] ERROR (kafka.utils.ZkUtils$) - Conditional update of path /brokers/topics/FunnelProto/partitions/4/state with data { "controller_epoch":3, "isr":[ 2, 5 ], "leader":2, "leader_epoch":2, "version":1 } and expected version 14 failed due to org.apache.zookeeper.KeeperException$BadVersionException: KeeperErrorCode = BadVersion for /brokers/topics/FunnelProto/partitions/4/state Any clues on what could be problem.. ?
