User: root is not allowed to impersonate root (state=08S01,code=0)

hive的客戶端連線服務使用metastore連線hiveserver2沒有出問題，而使用beeline連線hiveserver2卻出現如下問題

Error: Could not open client transport with JDBC Uri: jdbc:hive2://hadoop02:10000: Failed to open new session: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: root is not allowed to impersonate root (state=08S01,code=0)

查詢了網上的方法發現千篇一律，並沒有解決我的問題
在研究後將我的解決的方法分享給大家
首先在hive的伺服器端和客戶端兩個節點的core-site.xml配置檔案裡面加上下面的內容

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

然後將mysql-connector-java-5.1.28-bin.jar放入伺服器端和客戶端兩個節點的hive/lib下
mysql-connector-java-5.1.28-bin.jar

如此
再將RunJar程序殺死，重啟叢集就解決問題了
