shell定時建立Hive表分區,shellhive分區


首先看一下hive 的help命令:

[hdfs@xxx hive]$ hive  -hMissing argument for option: husage: hive -d,--define <key=value>          Variable subsitution to apply to hive                                  commands. e.g. -d A=B or --define A=B    --database <databasename>     Specify the database to use -e <quoted-query-string>         SQL from command line -f <filename>                    SQL from files -H,--help                        Print help information -h <hostname>                    connecting to Hive Server on remote host    --hiveconf <property=value>   Use value for given property    --hivevar <key=value>         Variable subsitution to apply to hive                                  commands. e.g. --hivevar A=B -i <filename>                    Initialization SQL file -p <port>                        connecting to Hive Server on port number -S,--silent                      Silent mode in interactive shell -v,--verbose                     Verbose mode (echo executed SQL to the                                  console)[hdfs@xxxx <span style="font-family: Arial, Helvetica, sans-serif;">hive]$ </span>


使用crontab定時給hive表增加表分區:




方法1:

 -e <quoted-query-string>         SQL from command line


執行命令:

[hdfs@xxxx hive]$ hive  --database gcld   -e  'alter table gcldlog  add partition (dt=\\'2015-06-14\\') location \\'2015-06-14\\'';


Logging initialized using configuration in file:/etc/hive/conf.dist/hive-log4j.properties
OK
Time taken: 1.097 seconds






方法2:

-i <filename>                    Initialization SQL file

編輯好sql命令:

alter table gcldlog  add partition (dt=‘2015-06-10') location '2015-06-10';

exit;(記得加上退出命令)


執行命令:

hive  --database gcld   -i /script/gcld/test.sql ;




這樣就可以實現shell動態給hive表增加分區表的操作。
