IllegalArgumentException：/tmp/zookeeper/myid 文件丢失

Question

我正在尝试按照 this gist 在多个 EC2 实例上配置 Kafka，但出现以下错误：

我正在运行这个命令：

$ bin/zookeeper-server-start.sh config/zookeeper.properties &

113308

错误：

[2017-03-22 08:21:00,314] ERROR Invalid config, exiting abnormally (org.apache.zookeeper.server.quorum.QuorumPeerMain)

我的zookeeper.conf如下图：

dataDir=/tmp/zookeeper
# the port at which the clients will connect
#clientPort=2181
clientPort=2080
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=0


server.1=ec2-<GLOBAL_IP_1>.amazonaws.com:2888:3888
server.2=ec2-<GLOBAL_IP_2>.amazonaws.com:2888:3888
#add here more servers if you want
initLimit=5
syncLimit=2
tickTime=2000

当服务器启动时，它通过查找知道它是哪个服务器 数据目录中的文件myid。

在dataDir 下创建一个名为myid 的文件，即为每个Zookeeper 服务器创建一个/tmp/zookeeper。

myid 文件应包含相应的服务器编号，以 ASCII 格式（例如：1）作为其中的唯一条目。
