Apache spark SPARK&x2B；独立群集：无法从另一台计算机启动辅助程序

我一直在设置Spark独立群集设置。我有两台机器；第一个（ubuntu0）既是主控者又是工作者，第二个（ubuntu1）只是工作者。已经为这两台机器正确配置了无密码ssh，并通过在两侧手动执行ssh进行了测试

现在，当我尝试./start-all.ssh时，主计算机（ubuntu0）上的主计算机和辅助计算机都已正确启动。这通过（1）可访问的WebUI（我的本地主机：8081）和（2）在WebUI上注册/显示的工作人员来表示。 但是，第二台机器（ubuntu1）上的另一个工作进程未启动。显示的错误为：

ubuntu1: ssh: connect to host ubuntu1 port 22: Connection timed out

现在这已经很奇怪了，因为我已经正确地将ssh配置为两边都没有密码。鉴于此，我访问了第二台机器，并尝试使用以下命令手动启动工人：

./spark-class org.apache.spark.deploy.worker.Worker spark://ubuntu0:7707
./spark-class org.apache.spark.deploy.worker.Worker spark://<ip>:7707

以下是my master and slave\worker spark-env.ssh的内容：

SPARK_MASTER_IP=192.168.3.222
STANDALONE_SPARK_MASTER_HOST=`hostname -f`

---

我应该如何解决这个问题？提前谢谢

对于那些在不同机器上启动工人时仍遇到错误的人，我只想分享一下，在conf/slaves中使用IP地址对我来说是有效的。

---

希望这有帮助

在/cong/slaves中使用主机名对我来说效果很好。 以下是我将采取的一些步骤

• 已检查SSH公钥
• scp/etc/spark/conf.dist/spark-env.sh发送给您的员工

我在spark-env.sh中的设置部分

导出独立\u SPARK\u MASTER\u主机=

hostname

导出SPARK\u MASTER\u IP=$STANDALONE\u SPARK\u MASTER\u主机

---

我猜你在配置中遗漏了一些东西，这是我从你的日志中了解到的

检查您的

/etc/hosts

，确保主设备的主机列表中的

ubuntu1

，并且其Ip与从设备的Ip地址匹配

在从属服务器的

SPARK env.sh

文件中添加

export SPARK\u LOCAL\u IP='ubuntu1'

---

今天我在RHEL6.7上运行spark 1.5.1时添加了类似的问题。 我有两台机器，它们的主机名是 -master.domain.com -slave.domain.com

我安装了spark的独立版本（针对hadoop 2.6的预构建）并安装了Oracle jdk-8u66

Spark下载：

wget http://d3kbcqa49mib13.cloudfront.net/spark-1.5.1-bin-hadoop2.6.tgz

Java下载

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u66-b17/jdk-8u66-linux-x64.tar.gz"

spark和java在我的主目录中解包后，我执行了以下操作：

在“master.domain.com”上，我运行了：

/sbin/start master.sh

webUI在（无从属运行）时可用

在“slave.domain.com”上，我尝试过：

/sbin/start-slave.shspark://master.domain.com:7077

失败，如下所示

注意：我没有在conf/spark-env.sh中添加任何额外的配置

注2：当查看master webUI时，顶部的spark master URL实际上是对我有用的URL，所以我怀疑你可以使用它

---

我希望这有帮助；）

我刚刚遇到了同样的问题，可以确认您确实必须使用web UI中显示的主URL启动工作程序（即使用与主URL相同的

$SPARK\u master\u IP

值）。
