>                 URL: https://issues.apache.org/jira/browse/IMPALA-1192
>             Project: IMPALA
>          Issue Type: Improvement
>          Components: Clients
>    Affects Versions: Impala 1.4.1
>            Reporter: John Russell
>            Priority: Minor

> It would be very convenient (from a documentation perspective) to have a way to set the prompt within an impala-shell session.
> The long impala-shell showing the host name and port number makes it difficult to format impala-shell output for use in documentation. Cloudera's PDF and HTML outputs both have problems displaying wide lines in code examples. Continuation lines are indented the same amount as the original >, so even when statements are split across lines there is not much room on each line.
> The shortest prompt is [localhost:21000] so that's what gets used consistently in the documentation, even if that's not best practice.
> If we wanted to show examples other than localhost, we don't have control over what's displayed, so we would have to edit the output to mask real Cloudera host names.
