Hello all,
I am trying to consume some topic using kafka-console-consumer.sh.
The problem is, I can consume nothing for a long time. there some infinite
print in the Client log like "SyncGroup for group example-group1 failed due to
UNKNOWN_MEMBER_ID, rejoining the group".
the print in the Server log is
2016-03-26 16:33:22,561 | INFO | [executor-Heartbeat] | [GroupCoordinator 2]:
Preparing to restabilize group example_gruoup1 with old generation 1 |
kafka.coordinator.GroupCoordinator (Logging.scala:68)
2016-03-26 16:33:22,561 | INFO | [executor-Heartbeat] | [GroupCoordinator 2]:
Group example_gruoup1 generation 1 is dead and removed |
kafka.coordinator.GroupCoordinator (Logging.scala:68)
2016-03-26 16:33:22,562 | INFO | [kafka-request-handler-6] | [GroupCoordinator
2]: Preparing to restabilize group example_gruoup1 with old generation 0 |
kafka.coordinator.GroupCoordinator (Logging.scala:68)
2016-03-26 16:33:22,563 | INFO | [kafka-request-handler-6] | [GroupCoordinator

kafka.coordinator.GroupCoordinator (Logging.scala:68)
Detail see the attachments, don't care about the time between client and
server log. (I did not collect the same time)
By the way, 1) producer works well.
2) the znode of example-group1 exist in zookeeper
/kafka/consumers.
3) zookeeper works well.
