Question

我已经开始了Metastore和hiveserver2

#./hive --service metastore
#./hive --service hiveserver2

当我在查询下面执行时

#./beeline -u jdbc:hive2://192.168.0.10:10000 -e 'select count(*) from test_tb'  --hiveconf hive.root.logger=DEBUG,console --verbose=true

抛出错误

Answer 1

我看到你正在使用Hiveserver2。对于这样的聚合，根据配置，我认为您可能需要在执行之前设置reducer的数量。使用Hive，您可以使用以下语法：

SET mapred.reduce.tasks=1

但是在Hive2上我注意到我需要使用：

SET mapreduce.job.reduces=1

我希望这有帮助！以前我有一个相同的错误消息，并改变这解决了我的问题。

Answer 2

这可能是权限问题，请尝试按以下方式启动beeline

直线

！连接jdbc：hive2：// hadoop7：10000 / default

输入您的用户名和密码

Answer 3

在运行查询之前添加以下代码段：

SET hive.auto.convert.join=false;
SET mapreduce.map.memory.mb = 16384; 
SET mapreduce.map.java.opts='-Djava.net.preferIPv4Stack=true -Xmx13107M';
SET mapreduce.reduce.memory.mb = 13107; 
SET mapreduce.reduce.java.opts='-Djava.net.preferIPv4Stack=true -Xmx16384M';
set hive.support.concurrency = false;

Answer 4

确认在我的情况下，这是由权限问题引起的（如wise_w所指出的），很奇怪的是，它看起来像普通select *可以正常工作，但是任何更复杂的方法都没有。

我尝试了以下操作：

$ beeline -u jdbc:hive2://server1:10000
(connected fine, no errors)
> select * from table1;
-> worked fine

> select count(*) from table1;
Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask (state=08S01,code=1)
or
ERROR : Job Submission failed with exception 'org.apache.hadoop.security.AccessControlException(Permission denied: user=anonymous, access=WRITE, inode="/user":hdfs:supergroup:drwxr-xr-x

解决方案始于wise_w建议

$ beeline --incremental=true
$ !connect jdbc:hive2://server1:10000/default
Enter username for jdbc:hive2://server1:10000/default: hive
Enter password for jdbc:hive2://server1:10000/default: **** (this is hive as well in my test setup)

->现在一切正常。

现在有一支班轮

$ beeline -u jdbc:hive2://server1:10000 -n hive -p hive --incremental=true

我觉得冲突来自事实，就像这样的联系

$ beeline -u jdbc:hive2://server1:10000

不会引发任何错误。

Answer 5

设置以下参数，在这种情况下很重要：

set mapred.job.queue.name=<your queue name>;
set mapreduce.job.reduces=1;

执行错误，从org.apache.hadoop.hive.ql.exec.mr.MapRedTask返回代码1（状态= 08S01，代码= 1）
