Question

您好我正在使用hadoop和HBase。当我尝试启动hadoop时，它开始很好但是当我尝试启动HBase时它在日志文件中显示异常。在日志文件中，hadoop拒绝连接localhost的端口54310。日志如下：

Answer 1

试试这个

使用＃在/ etc / hosts文件中注释127.0.1.1 然后将您的IP和计算机名称放在新行如果要使用localhost，请确保hosts文件中存在127.0.0.1 localhost 然后用配置文件替换所有出现的ip替换为localhost

如果你想使用ip而不是localhost，那么请确保你的hosts文件中有ip和等效的域名，并用你的ip替换所有localhost。

与namenode相关的问题通常是由于主机或IP配置错误而导致的。

Answer 2

尝试查看/ etc / hosts文件和/或将localhost分配给127.0.0.1。在您的示例中，它连接到192.168.15.20:54310，而不是127.0.0.1:54310

Answer 3

首先检查habse-site.xml中hbase.rootdir属性是否正在尝试连接到core-site.xml中为hadoop fs.default.name定义的同一端口。

hbase.rootdir是否设置为某个/tmp/hadoop位置？（因为那是侮辱）将其更改为指向hdfs所在的位置。

首先尝试http://localhost:50070并检查Namenode之类的东西： - IP - ： - port--。给我那个港口。

Answer 4

看看java.io.FileNotFoundException：/ hadoop / tmp / dfs / name / current / VERSION（Permission denied）

所以，首先 - 请看看你确实将hbase.rootdir设置为什么 - 无论是指向HDFS还是本地文件系统。我的示例（使用localhost进行伪分布式模式）：

    <configuration>
        <property>
            <name>hbase.rootdir</name>
            <value>hdfs://localhost:54310/hbase</value>
        </property>
        <property>
            <name>hbase.master</name>
            <value>127.0.0.1:60000</value>
        </property>
    </configuration>

接下来，查看您的日志似乎很可能您正在使用本地文件系统运行，并且您没有对HBase存储其数据的目录的读/写访问权限 - 请使用

进行检查

mcbatyuk:/ bam$ ls -l / |grep hadoop
drwxr-xr-x   3 bam   wheel       102 Feb 29 21:34 hadoop

如果您的base.rootdir在HDFS上，您似乎已经破坏了权限，因此您需要使用

进行更改

# hadoop fs -chmod -R MODE /hadoop/

或在$ HADOOP_HOME / conf / hdfs-site.xml中将属性dfs.permissions更改为false

Answer 5

不使用temp目录，而是将hdfs-site.xml中的“dfs.name.dir”配置到您有权读/写的目录。然后在格式化后启动namenode（命令是“hadoop namenode -format”）。完成后，尝试启动hbase。

HBase连接拒绝
