hive-相关报错处理${system:java.io.tmpdir}

 

 

 

在使用hive的时候启动成功

[root@localhost bin]# ./hive
which: no hbase in (/usr/local/hive/apache-hive-2.1.1-bin/bin:/usr/local/hive/apache-hive-2.1.1-bin/conf:/usr/local/java/jdk1.7.0_79/bin:/home/hadoop/cloud/apache-hive-2.1.1-bin/bin:/home/hadoop/cloud/apache-hive-2.1.1-bin/conf:/usr/local/java/jdk1.7.0_79/bin:/usr/local/java/jdk1.7.0_79/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/hadoop/hadoop-2.6.5/bin:/root/bin:/usr/local/hadoop/hadoop-2.6.5/bin:/usr/local/hadoop/hadoop-2.6.5/bin)

Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. tez, spark) or using Hive 1.X releases.

 

 在执行查询函数时却提示错误

hive> show functions;
OK
Failed with exception java.io.IOException:java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: ${system:user.name%7D
Time taken: 1.171 seconds

 

解决

将conf下面的hive-site.xml文件中的所有的system:user.name替换成用户名称，猜测可能是我使用的root管理员的情况下出现

替换后再次重启hive，执行show funcitons;成功

hive> show functions;
OK

可以看到错误元在system:user.name的配置。 
关联找到hive-site.xml里面，将{system:user.name}改为你的用户名， 
同时也可以将iotmp的对应配置修改成真实地址。 
${system:java.io.tmpdir} 改为真实物理路径。
