甚至名稱節點安全模式後，我無法啓動「蜂巢」

Question

但是多節點的Hadoop與

[acadgild@localhost ~]$ jps 
3378 NodeManager 
2841 NameNode 
3131 SecondaryNameNode 
3835 Jps 
3276 ResourceManager 
2942 DataNode 

工作正常，但是當我運行

[acadgild@localhost ~]$ hive 

它顯示了以下錯誤：

/usr/local/hive/bin/hive-config.sh: line 1: syntax error near unexpected token `(' 
/usr/local/hive/bin/hive-config.sh: line 1: `# Licensed to the Apache Software Foundation (ASF) under one or more'

得到這個錯誤後，我點擊命令

[acadgild@localhost ~]$ hdfs dfsadmin -safemode leave 
17/09/25 13:04:26 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 
Safe mode is OFF 

，並試圖再次 [acadgild@localhost ~] $不亦樂乎

但得到相同的錯誤和不可能開放的蜂巢PROMT。請幫我

「名稱節點在安全模式」是指沒有足夠的數據節點報告在 與塊報告。訪問Namenode UI以找出哪些數據節點 尚未報告。

或者，一個或多個datanode從其本地 文件系統中丟失了塊。您可以運行

"sudo -u hdfs hdfs fsck/-listcourruptblocks" 

命令來查看哪些文件已損壞
