服務 'HDFS' 檢查失敗：的java.net.UnknownHostException - Hortonworks

您好我M在Hortonworks性學習的，我米麪臨的一個問題，當過我服務 'HDFS' 檢查失敗：的java.net.UnknownHostException - Hortonworks

開放ambari - >文件查看，或蜂巢，豬。

我怎麼能解決這個問題，

問題檢測服務 'HDFS' 檢查失敗：的java.net.UnknownHostException：sandbox.hortonworks.com

塌陷堆棧跟蹤服務「HDFS '檢查失敗：

我是新手。請親引導我。我在窗口中使用docker的Hortonworks。

更新：

按先決條件，我已經加入像這樣

c/Windows/System32/Drivers/etc/hosts

本地主機名稱解析的DNS本身內部處理。

127.0.0.1 sandbox.hortonworks.com

192.168.XX.XX sandbox.hortonworks.com

直到現在我還得到錯誤。有人能幫我一下嗎。

只是爲了確保我瞭解你在做什麼 - 你在一個泊塢窗容器中運行Hortonworks的Hadoop，並試圖從主機的一些軟件連接到它？ – Kraylog

是實際運行docker容器中的hortonworks hadoop。我只是試圖創建表，並與Hive一起使用這個'http://hortonworks.com/hadoop-tutorial/how-to-process-data-with-apache-hive/' –

使用的第一個先決條件之一這個沙箱就是把'sandbox.hortonworks.com'放到你的'/ etc/hosts'文件中。你做過了嗎？ – Kraylog

看看在Docker中運行hortonworks hadoop的the prerequisites。您可能會丟失的是您的主機文件中的條目。下面是該鏈接的摘錄：

如果在Windows 7上，添加sandbox.hortonworks.com到您的主機列表，開放的git bash中，輸入以下命令，替換{主機名}與相應的主機爲您的沙箱：

echo '{Host-Name} sandbox.hortonworks.com' | tee -a /c/Windows/System32/Drivers/etc/hosts

謝謝，讓我檢查並讓你知道。這裏主機名是我的PC主機名localhost或（例如：CP00234）或ipaddress？ –

要麼應該工作。另外，請確保docker鏡像暴露出所需的端口。 – Kraylog

是的，thnx，我跟隨你的prerequsities，但也沒有解決問題。我在主機文件中添加了127.0.0.1 sandbox.hortonworks.com。 :( –

此錯誤是從沙箱虛擬機的內部發出的Hadoop的本身。更新Windows c/Windows/System32/Drivers/etc/hosts只會幫助您解析該主機名以使用主機名從瀏覽器訪問該web ui。 Hadoop Sandbox是一個虛擬機，您必須在虛擬機操作系統內更新它，這很可能是Linux。

您需要使用客戶端（如PuTTy）在虛擬機中打開終端會話，您可以在此免費下載。打開Putty輸入沙箱的ip地址，打開一個ssh連接到它。在putty的hostname字段中輸入127.0.0.1，然後爲端口輸入2222，然後按OK。您可能會被提示接受主機密鑰，請按OK。應該提示您輸入用戶名，輸入root作爲用戶名。它不應該要求輸入密碼。然後你應該在linux中有一個終端提示符，運行以下命令以將主機名稱回顯到/ etc/hosts文件。

cat/etc/hosts;

echo「127.0.0。1 sandbox.hortonworks.com沙箱本地主機」 >>/etc/hosts中

要檢查更新;

貓/ etc/hosts文件; 平sandbox.hortonworks.com

退出終端會話，然後嘗試。配置再次
