HBase連接拒絕

嗨，我正在使用hadoop和HBase.When我試圖啓動hadoop，它開始很好，但當我試圖啓動HBase它顯示日誌文件中的異常。在日誌文件中，hadoop拒絕localhost的端口54310上的連接。日誌在下面給出：HBase連接拒絕

檢查的錯誤配置??? – 2012-04-09 11:13:41

是的，我已經檢查過我的iptables，firestarter等。我認爲這不是端口問題，可能是配置錯誤。 – khan 2012-04-10 11:59:30

你可以把你的配置文件...我想一些如何hbase不能連接到hdfs ...可能是namenode沒有運行..查看配置文件將有所幫助。並檢查日誌namenode和所有你自己。 – 2012-04-10 12:38:09

試試這個

評論127.0.1。1在/ etc/hosts中使用文件＃然後把你的IP和計算機名在新行如果你想使用本地主機確保127.0.0.1本地主機是否有在您的主機文件然後替換在配置文件中IP的所有次數如果你想使用IP，而非輸入localhost然後確保IP和等效域名有沒有在你的hosts文件，併爲你的IP本地主機替換所有次數與本地主機

更換。如果防火牆阻止端口

一般名稱節點相關的問題的發生是由於主機或IP

沒錯。我嘗試了'telnet localhost 60000'，但它不能正常工作，但telnet 127.0.0.1 60000運行良好。 – 2014-09-24 07:22:59

嘗試尋找在/ etc/hosts文件和/或爲127.0.0.1分配本地主機。在你的榜樣它連接到192.168.15.20:54310，不127.0.0.1:54310

謝謝，但錯誤地我上傳了我的舊日誌。無論如何，這個問題仍然發生在127.0.0.1:54310的localhost i-e上。現在通過前進，最後我發現了這個問題。其實當我嘗試啓動hadoop時，它的所有服務，如 TaskTracker，JobTracker，DataNode，SecondaryNameNode正在運行，除了NameNode.So，HBase無法找到hadoop，因爲namenode不在。請引導我爲什麼發生這種情況 – khan 2012-04-10 12:49:42

試着把您的Hadoop/conf目錄和HBase的/ conf目錄這裏的文件，以便我可以檢查 – abatyuk 2012-04-11 07:13:40

我已經把他們 – khan 2012-04-12 13:09:48

首先檢查在habse-site.xml財產hbase.rootdir試圖在core-site.xml Hadoop的定義爲fs.default.name連接到同一個端口。

是hbase.rootdir是否設置爲/tmp/hadoop位置？（因爲這是詭辯）將其更改爲指向您的hdfs所在的位置。

首先嚐試http://localhost:50070並檢查Namenode之類的東西：--IP - ： - port--。給我那個港口。

2012-04-10 13:08:59

在java.io.FileNotFoundException看看：/ Hadoop的/ tmp目錄/ DFS /名/電流/版本（拒絕）

所以，首先 - 請你有什麼設置爲HBase的。確實是rootdir--無論是指向HDFS還是本地文件系統。我的例子（與本地主機的僞分佈式模式）：

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

接下來，看你的日誌，似乎最有可能您正在使用本地文件系統中運行，您不必讀/寫訪問其中HBase的存儲其數據的目錄 - 與

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

檢查，如果你的base.rootdir是HDFS你似乎有破損的權限，所以你需要用

# hadoop fs -chmod -R MODE /hadoop/

，或者更改在您的$ HADOOP_HOME/conf/hdfs-site.xml中將屬性dfs.permissions更改爲false

@雪利酒汗因此，基本上，你在提的評論[]（http://stackoverflow.com/a/10106233/1053990）您的hadoop tmp目錄無法訪問。首先更改權限（例如'sudo chmod -R a + rw/hadoop'），然後格式化namenode（hadoop namenode -format）。 – abatyuk 2012-04-11 17:01:33

是的 - 我已經改變了權限但仍然沒有輸出 – khan 2012-04-12 13:10:24

而不是使用臨時目錄，將hdfs-site.xml中的「dfs.name.dir」配置到您的目錄有權讀取/寫入。然後在格式化後啓動namenode（命令是「hadoop namenode -format」）。一旦完成，請嘗試啓動hbase。
