通过hue的web界面进行hive的sql查询，无法显示结果并报错timeout
报错如下：

解决方法：
修改配置文件
/home/hadoop/.versions/hue-3.10.0/desktop/conf/hue.ini
server_conn_timeout=120
改为，重启hue服务，好像没用
server_conn_timeout=1200
搜索了下网上说，如果通过Hue的web来执行Hive查询，需要启动HiveServer2服务
查看配置conf/hue.ini，连接的是uhadoop-bwgkeu-master2的10000端口，连接这个master2通过ps -ef|grep hive发现已经启动了的，于是重启服务，问题解决
[hadoop@uhadoop-bwgkeu-master2 log]$ ps -ef|grep hive

简单的hive查询验证是否能够正常查询：
SELECT s07.description, s07.salary, s08.salary,
s08.salary - s07.salary
FROM
sample_07 s07 JOIN sample_08 s08
ON ( s07.code = s08.code)
WHERE
s07.salary < s08.salary
ORDER BY s08.salary-s07.salary DESC
LIMIT 1000
简单hive查询的例子
SELECT s07.description, s07.salary
FROM
sample_07 s07
LIMIT 10
hive_shell查询：
# hive
hive> select * from tbl_push_user_req limit ;
