Answer 1

Mapreduce 作業失敗，因為它無法訪問 HDFS，因為There are 0 datanode(s) running and 0 node(s) are excluded in this operation.

並且從datanode的日志中了解到， Datanode守護進程由於Incompatible clusterIDs的clusterIDs而無法注冊到HDFS集群。

當一個namenode被格式化（在安裝和設置過程中）時，會生成一個clusterID ，並且這個clusterID在每個守護進程初始化時存儲在它們的VERSION文件中。 這個 clusterID 充當數據節點的標識符，讓它們在停止和啟動時重新加入集群。

當 namenode 在活動集群上格式化並且其他守護程序未重新初始化時，節點之間可能會發生不兼容的 clusterID。

為了讓集群恢復原狀，

1. 停止集群
2. 刪除以下目錄的內容C:\hadoop\hdfstmp , C:\hadoop\data\namenode , C:\hadoop\data\datanode
3. 格式化名稱節點
4. 啟動集群

您已重新復制 Mapreduce 作業所需的數據並運行該作業。

Answer 2

我沒有關閉和重新啟動集群的選項。 但是，運行以下命令解決了該問題，而不會導致我看到的任何其他問題。

hdfs dfsadmin -safemode leave
