Question

我尝试运行地图缩减作业以使用Hive获取表中的用户数。我这样做了一个AccessControlException。

命令提示符上的消息：

hive> select count(*) from bxbookratings;

Number of reduce tasks determined at compile time: 1
In order to change the average load for a reducer (in bytes):
  set hive.exec.reducers.bytes.per.reducer=<number>
In order to limit the maximum number of reducers:
  set hive.exec.reducers.max=<number>
In order to set a constant number of reducers:
  set mapreduce.job.reduces=<number>

请帮我解决这个问题。

Answer 1

您可以通过在hdfs-site.xml

中将以下属性设置为false来禁用hdfs权限

<property>
<name>dfs.permissions.enabled</name>
<value>false</value>
</property>

将此属性设置为false后，需要重新启动hdfs。

此外，此hdfs_permissions_guide页面建议使用net group窗口来管理组。我认为您可以使用此功能在hive组中添加nikhilbarar用户：see-net-group-usage.
