登陸hadoop報錯

1.運行環境變量，獲取keytab票據：

source component_env
klist -kt ***.keytab
kinit -kt ********

2.登錄過程報錯：

①.bomc@HN2-103-H13-02Rs-BDI2:~> cd hadoopclient/
-bash: cd: hadoopclient/: Permission denied 報錯緣由：權限問題 解決辦法：切換到root用戶：chown -R *：* hadoopclient/ ②.bomc@HN2-103-H13-02Rs-BDI2:~/hadoopclient> kinit -kt *********** kinit: Resource temporarily unavailable while getting initial credentials 報錯緣由：通常來講是網絡問題，檢查/etc/hosts文件，沒問題後，找到環境變量中用到的文件是生產環境的信息， 解決辦法：我從其餘機器中scp了一個文件過來，從新source了一下環境變量 ③.bomc@HN2-103-H13-02Rs-BDI2:~/hadoopclient> cd hadoop/bin/ bomc@HN2-103-H13-02Rs-BDI2:~/hadoopclient/hadoop/bin> ./hadoop fs -ls / ./hadoop: line 144: /usr/jdk64/jdk1.7.0_67/bin/java: No such file or directory ./hadoop: line 144: exec: /usr/jdk64/jdk1.7.0_67/bin/java: cannot execute: No such file or directory bomc@HN2-103-H13-02Rs-BDI2:~/hadoopclient/hadoop/bin> 報錯緣由：沒有找到jdk文件 解決辦法：從其餘機器中scp了一個文件過來，scp -r jdk64/ root@10.243.160.101:/usr/ ④.bomc@HN2-103-H13-02Rs-BDI2:~/hadoopclient/hadoop/bin> ./hadoop fs -ls / Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0
