方法1.配置zk问题(kafka的consumer配置)
zookeeper.session.timeout.ms=5000
zookeeper.connection.timeout.ms=10000
rebalance.backoff.ms=2000
rebalance.max.retries=10
方法2. 在spark读取kafka的代码修改
val kafkaParams = Map(
“zookeeper.connect” -> zkQuorum,
“group.id” -> “default”,
“auto.offset.reset” -> “largest”,
“zookeeper.session.timeout.ms” -> “6000”,
“zookeeper.connection.timeout.ms” -> “6000”,
“zookeeper.sync.time.ms” -> “2000”,
“rebalance.backoff.ms” -> “10000”,
“rebalance.max.retries” -> “20”
)
KafkaUtils.createStream[String, String, StringDecoder, StringDecoder](ssc, kafkaParams, topic, StorageLevel.MEMORY_ONLY_SER).map(_._2)
