Hi again,
Does my zkRoot need to equal the value that is actually in zookeeper ? (I'm
also new to zookeeper0
Here is Zookeeper:
[zk: 127.0.0.1:2181(CONNECTED) 8] ls /brokers/topics/mytopic/partitions
[1, 0]
And here is what I pass into spoutConfig:
SpoutConfig spoutConfig = new SpoutConfig(hosts, "mytopic",
"/brokers/mytopic", "1");
Right before the crash, debugging statements say:
7188 [Thread-13-kafka] INFO storm.kafka.PartitionManager - Read partition
information from: /brokers/mytopic/1/partition_1 --> null
7332 [Thread-13-kafka] INFO storm.kafka.PartitionManager - No partition
information found, using configuration to determine offset
