Description

When LDAP authentication is enabled in Impala, impala-shell always prompts for a password when trying to connect to an Impala daemon, which makes it very hard to use impala-shell in a shell script (where to store the password?)
Please make impala-shell support reading password from a command line parameter or from a password file, just like what beeline does.
