Hive启动时报错，报错信息如下：
Logging initialized using configuration in jar:file:/usr/local/opt/hive-0.14.0/lib/hive-common-0.14.0.jar!/hive-log4j.properties

第一种解决方案：
这个问题是由于hive版本较高，hadoop版本较低，不相匹配造成的，解决方法时降低hive的版本，比如降低到hive-0.9.0。
第二种解决方案：
1、在hive-site.xml中添加如下配置：
<property>
<name>fs.permissions.umask-mode</name>
<value>022</value>
<description> Setting a value for fs.permissions.umask-mode to work around issue in HIVE-6962.
It has no impact in hadoop 1.x line on hdfs operations.
</description>
</property>
2、修改hadoop hdfs tmp文件夹的权限
hadoop fs -chmod -R 777 /tmp
3、将hive-site.xml中所有的配置值含有"system:java.io.tmpdir"的配置项替换为绝对路径
在hive-0.14.0下创建临时文件目录hive_tmp：mkdir hive_tmp
将system开始的路径替换为/usr/local/opt/hive-0.14.0/hive_tmp
