## 1、启动Kafka出现以下错误： ##

[root@hadoop01 kafka_2.13-2.6.0]# ./bin/kafka-server-start.sh config/server.properties 
    Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c0000000, 1073741824, 0) failed; error='Not enough space' (errno=12)
    #
    # There is insufficient memory for the Java Runtime Environment to continue.
    # Native memory allocation (mmap) failed to map 1073741824 bytes for committing reserved memory.
    # An error report file with more information is saved as:
    # /opt/kafka_2.13-2.6.0/hs_err_pid21451.log

## 2、问题 ##

启动时报错，大概意思是内存不足。

## 3、解决方案 ##

# 修改前
    export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
    # 修改后
    export KAFKA_HEAP_OPTS="-Xmx256M -Xms128M"。

## 重新启动即可 ##
