CDH 安装hue报错Unexpected error. Unable to verify database connection

1, 查看具体报错原因： libmysqlclient_r.so.16: cannot open shared object file: No such file or directory

tail -f /opt/cloudera*/logs/cloudera-scm-server/cloudera-scm-server.log ，查看报错信息如下：

 exec /opt/cloudera/parcels/CDH-5.12.0-1.cdh5.12.0.p0.29/lib/hue/build/env/bin/hue is_db_alive

----解决： 在别的虚拟机中复制该文件，上传到此机器，最后移动到 /usr/lib目录下：
mv ~/libmysqlclient_r.so.16  /usr/lib/                        

2， 登陆hue

用户名密码： hue/hue

create database   if not exists test;
use test;
create table per(id int ,name varchar(10));
insert into per values(1,'a'),(2,'b');
select * from per;

2, 配置hue查询hbase数据

a. 启动HBase Thrift Server

确认启动了 HBase Thrift Server服务， 并且在hue属性中选择HBase Thrift Server服务器使用 Hue HBase Browser 应用程序

b. hbase-site.xml配置

<property>
  <name>hbase.thrift.support.proxyuser</name>
  <value>true</value>
</property>
<property>
  <name>hbase.regionserver.thrift.http</name>
  <value>true</value>
</property>

c, core-site.xml 配置

<property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hbase.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hbase.groups</name>
<value>*</value>
</property>
