myuser@namenode:/opt/hive/current/bin$

尝试一：

myuser@namenode:~$ sudo hive
sudo: hive: command not found
#必须到执行文件路径，sudo之后还必须指定下环境变量
myuser@namenode:/opt/hive/current/bin$ sudo source /etc/profile ; ./hive

参考
跟在crontab中执行代码情况类似hive: command not found错误解决

尝试二

把hive参数hive.exec.scratchdir 设置的目录,一般为 /tmp/hive权限调整为777即可.即： chmod -R 777 /hive/tmp

<property>
  <name>hive.exec.scratchdir</name>
  <value>/hivetest/hive</value>
  <description>HDFS root scratch dir for Hive jobs which gets created with write all (733) permission. For each connecting user, an HDFS scratch dir: ${hive.exec.scratchdir}/&lt;username&gt; is created, with ${hive.scratch.dir.pe
  rmission}.</description>
</property>

发现已经是了

myuser@namenode:/opt/hive/current/bin$ hdfs dfs -ls  /hivetest/
17/04/26 15:17:09 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

hive错误：Exception in thread "main" java.lang.RuntimeException: java.io.IOException: Permission denied

尝试三

修改用户组

usermod -a -G hive  myuser
#检查修改
myuser@namenode:/opt/hive/current/bin$ groups
myuser adm cdrom sudo dip plugdev lpadmin sambashare

myuser@namenode:/opt/hive/current/bin$ groups myuser
myuser : myuser adm cdrom sudo dip plugdev lpadmin sambashare hive

还是不行，报原来的错误。

尝试四

切换用户

myuser@namenode:/opt/hive/current/bin$ su hive
#密码：123456
Password:
hive@namenode:/opt/hive/current/bin$

解决
