解决方法：
修改kafka broker的server.property的配置文件如下：
#加大每一条message的最大值
message.max.bytes 默认为1000000 byte
调整后：
message.max.bytes=5252880
replica.fetch.max.bytes=6252880
request.timeout.ms=600000

[@zw ~]# kafka-topics.sh --alter --topic mm-recommend-dev --config max.message.bytes=5252880 --zookeeper ip:2181/kafka-0.10.2.1-test
WARNING: Altering topic configuration from this script has been deprecated and may be removed in future releases.
Going forward, please use kafka-configs.sh for this functionality
Updated config for topic "mm-recommend-dev".

新的方式
bin/kafka-configs.sh --zookeeper localhost:2181 --entity-type --alter --topic mm-recommend-dev --config max.message.bytes=5252880
