登陆hadoop报错

1.运行环境变量，获取keytab票据：

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

2.登录过程报错：

①.bomc@HN2-103-H13-02Rs-BDI2:~> cd hadoopclient/
-bash: cd: hadoopclient/: Permission denied 报错缘由：权限问题 解决办法：切换到root用户：chown -R *：* hadoopclient/ ②.bomc@HN2-103-H13-02Rs-BDI2:~/hadoopclient> kinit -kt *********** kinit: Resource temporarily unavailable while getting initial credentials 报错缘由：通常来讲是网络问题，检查/etc/hosts文件，没问题后，找到环境变量中用到的文件是生产环境的信息， 解决办法：我从其余机器中scp了一个文件过来，从新source了一下环境变量 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> 报错缘由：没有找到jdk文件 解决办法：从其余机器中scp了一个文件过来，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
