Hive之权限

一、库级的权限

-- 授予所有权限给某个用户
grant all on msta to user {userName};
-- 授权admin privilege权限
grant ADMIN PRIVILEGE on database {dbName} to user {userName};

-- 授予某个库的权限给某个用户
grant select on database {dbName} to user {userName};
grant insert on database {dbName} to user {userName};
grant update on database {dbName} to user {userName};
grant delete on database {dbName} to user {userName};

-- 回收某个库的权限给某个用户
revoke select on database {dbName} from user {userName};
revoke insert on database {dbName} from user {userName};
revoke update on database {dbName} from user {userName};
revoke delete on database {dbName} from user {userName};

-- 查看指定用户在所有库下面的权限
show grant user {userName};
-- 查看指定用户在某个库的权限
show grant user {userName} on database {dbName};

 

二、表级的权限

-- 授予表的权限给某个用户
grant create on database {dbName} to user {userName};
grant select on table {dbName}.tableName to user {userName};
grant insert on table {dbName}.tableName to user {userName};
grant update on table {dbName}.tableName to user {userName};
grant delete on table {dbName}.tableName to user {userName};


-- 回收某个用户的表的权限
revoke create on table {dbName}.tableName from user {userName}; 
revoke select on table {dbName}.tableName from user {userName};
revoke insert on table {dbName}.tableName from user {userName};
revoke update on table {dbName}.tableName from user {userName}; 
revoke delete on table {dbName}.tableName from user {userName};

-- 查看指定用户在指定表的权限
show grant user {userName} on table {dbName}.{tableName};
