Hive的日志操作

想要看hive的日志，我们查看/home/hadoop/hive/conf/hive-log4j2.properties

# list of properties
property.hive.log.level = INFO
property.hive.root.logger = DRFA
property.hive.log.dir = ${sys:java.io.tmpdir}/${sys:user.name}
property.hive.log.file = hive.log
property.hive.perflogger.log.level = INFO

红色部分说明了hive的日志目录，但是我们查看 echo ${sys:java.io.tmpdir} 是没有输出的，为空，其实日志目录在系统的/tmp/hostname/hive.log

[hadoop@master hadoop]$ pwd
/tmp/hadoop
[hadoop@master hadoop]$ ls -rlt
total
-rw-rw-r--.  hadoop hadoop   Jan  : hive.log.--
-rw-rw-r--.  hadoop hadoop  Mar  : hive.log.--
-rw-rw-r--.  hadoop hadoop    Apr   : hive.log.--
-rw-rw-r--.  hadoop hadoop    Apr   : stderr
-rw-rw-r--.  hadoop hadoop   Apr   : hive.log

在hive的安装目录，新建一个logs目录，来存储日志文件

[hadoop@master hive]$ pwd
/home/hadoop/hive
[hadoop@master hive]$ mkdir logs

修改配置文件 hive-log4j2.properties

property.hive.log.dir = /home/hadoop/hive/logs

退出hive

[hadoop@master sbin]$ hive

Logging initialized using configuration in file:/home/hadoop/hive/conf/hive-log4j2.properties Async: true
Hive-on-MR is deprecated in Hive  and may not be available in the future versions. Consider using a different execution engine (i.e. spark, tez) or using Hive .X releases.
hive> show databases;
OK
db_hive
default
Time taken: 3.857 seconds, Fetched:  row(s)
hive> use db_hive;
OK
Time taken: 0.024 seconds
hive> exit ;

重新启动hive

[hadoop@master logs]$ pwd
/home/hadoop/hive/logs
[hadoop@master logs]$ ls -rlt
total
-rw-rw-r--.  hadoop hadoop  Apr   : hive.log

可以看到hive的日志已经更改路径了

可以看hive中的变量：

hive> set;

...
...
system:sun.java.launcher=SUN_STANDARD
system:sun.jnu.encoding=UTF-
system:sun.management.compiler=HotSpot -Bit Tiered Compilers
system:sun.os.patch.level=unknown
system:user.country=US
system:user.dir=/home/hadoop/hadoop-2.7./sbin
system:user.home=/home/hadoop
system:user.language=en
system:user.name=hadoop
system:user.timezone=America/Los_Angeles

设置属性在启动的时候

[hadoop@master sbin]$ hive -help

                                  commands. e.g. -d A=B or --define A=B
