kafka 啓動 報錯cannot allocate memory，即內存不足

錯誤提示：
Java Hotspot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c5330000, 986513408, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 986513408 bytes for committing reserved memory.
# An error report file with more information is saved as:
# hs_err_pid5535.log
解決辦法：
將 kafka-server-start.sh的
export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
修改成
export KAFKA_HEAP_OPTS="-Xmx256M -Xms128M"
由於個人內存是1G
