FATAL Fatal error during KafkaServerStartable startup. java.lang.OutOfMemoryError: Java heap space

今天搭建了kafka單機版用於測試，配置好以後啓動kafka時出現了內存溢出的問題，如下： 

[2016-10-22 10:39:39,112] INFO [Kafka Server 0], shut down completed (kafka.server.KafkaServer)
[2016-10-22 10:39:39,113] FATAL Fatal error during KafkaServerStartable startup. Prepare to shutdown (kafka.server.KafkaServerStartable)

解決方法：

編輯 kafka/kafka-server-start.sh 這個啓動文件，修改 KAFKA_HEAP_OPTS 這個參數，默認的參數是 export KAFKA_HEAP_OPTS="-Xmx512m -Xms512m"，增大內存即可，export KAFKA_HEAP_OPTS="-Xmx1g -Xms1g"，再次啓動問題解決。
