解决一些hive中的一些错误和解决方式

报错【Hive启动】_Exception in thread “main“ java.lang.NoSuchMethodError: 

1. 触发报错

    1.  hive 启动 

    2. 初始化元数据库(derby)   bin/schematool -dbType derby -initSchema

2. 报错信息

　　　　Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;Ljava/lang/Object;)V

3. 解决

　　hadoop和hive的两个guava.jar版本不一致

　　两个位置分别位于下面两个目录：

　　- /usr/local/hive/lib/

　　- /usr/local/hadoop/share/hadoop/common/lib/

4. 报错原因

　 删除低版本的那个，将高版本的复制到低版本目录下

在Hive中创建一个表然后想向表中插入数据，每次插入数据都会出现如下异常；

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask

 报错的原因是找不到队列user hyxy to unknown queue: defualt，因为之前在yarn中设置了队列，而hive语句最终走的底层是MapReduce，所以任然需要资源调度，我们设置一个队列就好了：

hive> set mapreduce.job.queuename=max;

设置上此操作后就能正常插入数据了

Error: Could not open client transport with JDBC Uri: jdbc:hive2://node1:10000:

在使用beeline上使用!connect jdbc://hive2://node1:10000出现报错 

修改hadoop中core-site.xml

先关闭hadoop集群再修改：

#core-site.xml的配置
	
     		hadoop.proxyuser.root.hosts
     		*
	
	
     		hadoop.proxyuser.root.groups
     		*
	

root为当前我操作hive的用户名,如果操作的用户名不是root需要修改用户名。

由于我之前没有修改用户名导致出现现在的错误,改成我操作的用户root就成功了

配置文件功能是使当前用户可以操作任何主机和用户组
