Hive CLI的命令都是怎樣的,針對這個問題,這篇文章詳細介紹了相對應的分析和解答,希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。

這些命令可以直接cli或者beeline里面執行。

quit 
exit

Use quit or exit to leave the interactive shell.

reset

Resets the configuration to the default values (as of Hive 0.10: see HIVE-3202). Any configuration parameters that were set using the set command or -hiveconf parameter in hive commandline will get reset to default value.

Note that this does not apply to configuration parameters that were set in set command using the "hiveconf:" prefix for the key name (for historic reasons).

set <key>=<value>

Sets the value of a particular configuration variable (key). 
Note: If you misspell the variable name, the CLI will not show an error.

set

Prints a list of configuration variables that are overridden by the user or Hive.

set -v

Prints all Hadoop and Hive configuration variables.
