linux - Hadoop(NameNode、DataNode 和 SecondaryNameNode)未启动

Question

嗨，我是 Hadoop 的新手，并试图让它在我的本地机器上运行。但是每次我运行 hdfs namenode -format 然后 start-dfs.sh 和 start-yarn.sh 或 start-all.sh 时。它记录了这些文件，我无法弄清楚哪里出了问题。

请查看下面的日志文件

其他类似的数据节点，secondarynod 和 yarn 也是如此。
我可以把我的 body 放在正确的方向吗？谢谢

Answer 1

此日志中哪些消息与您有关？

它看起来像一个典型的 namenode 启动日志，我没有看到任何致命的东西。

有一些关于复制 block 不足的消息，但这应该只是一个警告。看起来您的默认 block 复制设置为 1，通常为 3。您可以运行任何 hadoop 命令吗？

hadoop fs -ls /

如果是这样，您可以使用命令检查 Hadoop 2.7.3 版本中的设置 block 大小
hdfs getconf -confKey dfs.blocksize

如果它说找不到命令，则可能没有将它添加到您的用户 $PATH 环境变量中以执行。可执行文件本身应该存在于/usr/local/hadoop/bin、/usr/local/hadoop/bin/hadoop/或附近。

我不确定您正在运行哪个 Hadoop 发行版，但是您可以更新集群用来更新您的 hdfs-site.xml 的 hdfs-site.xml，它通常位于您的 hadoop home 中或以符号方式链接到/etc/hadoop/conf/hdfs-site.xml。在 hdfs-site.xml 中找到 dfs.replication 的属性。您会注意到该值为 1。您可以将其更改为您选择的值，3 通常是一个很好的复制因子。如果这样做会破坏环境，请进行更改然后开始备份。

也有可能是因为您刚刚格式化了您的 namenode 然后开始 block 尚未复制。名称节点的主要目的是通过编辑文件跟踪您的 block 。因此，如果您刚刚格式化然后启动它，名称节点将需要几分钟时间让数据节点启动，发送它们的心跳，然后报告 block ，并复制它们。

您也可以在 Linux 命令行上运行以下命令来检查端口监听的状态；

sudo lsof -i tcp | grep -i LISTEN

您应该看到端口 9000聆听，如果名称节点已启动，也可能是 8020。顺便说一下，这些端口与数据节点将使用的端口不同。
如果您检查 *site.xml 文件，它会告诉您集群的属性，包括主机名、端口和正在运行的服务以及其他集群信息。

如果你去 http://hostname.example.com:50070/ 你也应该有一个 web ui这应该给你基本的地位。

hadoop需要注意的重要配置文件有:

hadoop-env.sh(设置您的 HADOOP_HOME 变量和 JAVA_HOME)。它应该在/usr/local/hadoop/文件夹中或周围，具体取决于您的发行版。

hdfs-site.xml、core-site.xml、yarn-site.xml、mapred-site.xml 和其他 *-site.xmls 用于其他服务，例如 hive、spark 等。

通常一个名为/etc/hadoop/conf 的目录象征性地链接到它们在每个节点上的实际位置。这些文件中的属性决定了您的大部分集群设置。

请记住，Hadoop 的文件系统 HDFS 不是操作系统文件系统上的路径。如果您在 HDFS 中有一个路径，例如/user/hive/warehouse，它只存在于 hdfs 中，而不存在于服务器文件系统中。所以你不能 cd/user/hive/warehouse。您将需要使用客户端软件或 hadoop fs 命令与 hdfs 交互。

**

如果您的集群正在运行，您可以在 Linux 终端上运行以下命令(如果安装没有更新您的 $PATH 以包含它，您可能必须转到/usr/local/hadoop/bin 文件夹来修复可执行文件)；

hdfs getconf -namenodes
-secondaryNameNodes
-backupNodes
-includeFile
-excludeFile
-nnRpcAddresses
-confKey [key]

HDFS版本

为 HDFS 命令轻松启用调试；

HADOOP_ROOT_LOGGER=调试，控制台 hdfs dfs -ls /
日志应该以各种名称存储在/var/log 中，具体取决于集群上运行的服务。

还要确保根据所有节点上的操作系统禁用了任何系统防火墙，包括 iptables/firewalld。 Hadoop 将使用各种端口在非标准端口上的节点之间进行通信。因此，如果您打开了 iptables/firewalld，即使服务已启动，连接也会被拒绝，使节点看起来离线。
