在Apache Hadoop單節點設置中的start-all.sh失敗

Question

我在Ubuntu 12.04上安裝了Apache Hadoop 1.0.4。我按照http://hadoop.apache.org/docs/stable/single_node_setup.html的指示，到達了「執行」部分。我在$ bin/start-all.sh上失敗了，錯誤信息如下。我的用戶名是anson。

Answer 1

您用於啓動hadoop的用戶沒有/var/log的權限。檢查用戶的權限/var/log/。

另一種方式，您可以更改hadoop基本目錄跨hadoop.tmp.dir配置。

Answer 2

改變目錄的所有者，並權限設置爲755

Answer 3

這聽起來像你安裝了Hadoop的Debian軟件包，和你想運行start-all.sh作爲非root用戶。

這裏有一些想法：

1. 嘗試繼「獨立操作」指令，寫，應該工作。
2. 請按照所述的「僞分佈式操作」部分嘗試，但有一個例外：sudo start-all.sh而不是bin/start-all.sh。
3. 嘗試徹底卸載Debian軟件包，改爲使用Hadoop發行版tarball。

如果你去的壓縮包選項，首先清除的Debian軟件包：

sudo apt-get purge hadoop 

確保你沒有設置任何Hadoop的特定的環境變量。如果你從那個命令，重啓任何輸出或手動unset含HADOOP任何環境變量

set | grep HADOOP 

：這應該返回任何內容。

在這一點上，你應該能夠爆炸壓縮包，並按照書面（並且作爲非root用戶）遵循「僞分佈式操作」指南。

有兩個tarball。 hadoop-1.0.4.tar.gz包含來源和文檔，hadoop-1.0.4-bin.tar.gz不包含。要麼工作。
