integrate ldap to impala

Explorer

Hi,i must say my english is bad,thanks all for my issule:

I had already integrate ldap to impala ,everytime i input impala-shell -l -u root , It will prompt me password。

My question comes:I want to integrate password to the console like this  impala-shell -l -u root -p root,

i read the document of impala ,it tells me with a argument as  --ldap_password_cmd,but i really dont know how to input it's value ,can anyone tell me ?

thaks very much!

Re: integrate ldap to impala

The argument should be a shell command that prints the password. E.g. if you store the password in /home/example/ldap_password.txt

 

--ldap_password_cmd='cat /home/example/ldap_password.txt'

Be sure that 'a.txt' doesn't include a trailing newline or other whitespace.

Maybe try --ldap_password_cmd='echo ' first?
