启动Hive的时候有很多WARN和INFO信息，hivewarninfo信息

配置好hive后，输入hive命令启动时会出现许多INFO和WARN信息。如下：

15/04/21 11:31:45 INFO Configuration.deprecation: mapred.input.dir.recursive is deprecated. Instead, use mapreduce.input.fileinputformat.input.dir.recursive
15/04/21 11:31:45 INFO Configuration.deprecation: mapred.max.split.size is deprecated. Instead, use mapreduce.input.fileinputformat.split.maxsize

原因是在新的Hadoop版本中，很多参数都废弃了，所以这些信息一定会显示出来。解决的办法是在$HADOOP_HOME/etc/hadoop/log4j.properties中将log4j.logger.org.apache.hadoop.conf.Configuration.deprecation打开。如下：

# Uncomment the following line to turn off configuration deprecation warnings.
log4j.logger.org.apache.hadoop.conf.Configuration.deprecation=WARN

无需重启Hadoop，只需要重新启动hive就会发现这些INFO都不见了。但是WARN还是会在。
