amazon-web-services - Spark 无法使用公共(public) IP 在端口 7077 上绑定(bind)

Question

我已经在 AWS 上安装了 spark。
当我尝试在 AWS 上执行时，它可以工作，但 spark 不起作用，当我检查 sparkMaster 日志时，我看到了下一个:

Spark Command: /usr/lib/jvm/java-8-oracle/jre/bin/java -cp /home/ubuntu/spark/conf/:/home/ubuntu/spark/jars/* -Xmx1g org.apache.spark$

我的/etc/hosts 是下一个:

127.0.0.1  localhost

    52.211.60.97    server1
    52.210.246.199  client1
    52.211.71.126   client2
    52.211.20.213   client3

    # The following lines are desirable for IPv6 capable hosts
    ::1     ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters

这是我的 spark-env.sh:

export SPARK_WORKER_MEMORY=512m
export SPARK_EXECUTOR_MEMORY=512m
export SPARK_WORKER_INSTANCES=1
export SPARK_WORKER_CORES=1
export SPARK_WORKER_DIR=/home/ubuntu/spark
export SPARK_LOCAL_IP=52.211.60.97
export SPARK_MASTER_IP=52.211.60.97
export SPARK_MASTER_WEBUI_PORT=4041

我尝试过相同的剧本，但使用带有私有(private)实例和 VPN 的 AWS VPC，它运行良好。所以我认为公共(public)IP有什么问题，也许亚马逊封锁了公共(public)IP上的一些端口？或者可能是什么问题？

Answer 1

我也面临着类似的问题。
这是因为 spark master 无法打开 SPARK_MASTER_IP 上指定的端口。
首先，通过 hostname 找到您的主机名命令。
之后，确保您的机器 ip 地址在 /etc/hosts映射到给定的主机名。
之后，将该主机名用于 SPARK_MASTER_IP。
对于这个问题，集群模式下也可以提export SPARK_LOCAL_IP=127.0.0.1 .
