Hiya,
Thanks for the ping, Larry. I wasn't subscribed (but am now :wink:)
Ben -- Remember that there is a difference between the JDBC URL and the
HTTP URL. The HTTP URL is how your client knows how to "find" the Knox
gateway service and then how the gateway knows how to forward your
request to the back-end Avatica server. The JDBC URL is used to state
what JDBC Driver class should be used and the client-side options that
driver should use.
Thus, your second example would not be expected to work.
I'm guessing that your first example did work. There isn't presently any
UI component to the Avatica server. It's only meant to be used with a
proper driver to programmatically access the server, e.g. the Avatica
JDBC driver, the phoenix-pythondb driver, or the Golang driver.
The following are two open issues that might help in the future.
https://issues.apache.org/jira/browse/CALCITE-1195
https://issues.apache.org/jira/browse/CALCITE-1405
If you're "docker-comfortable", you can try the following image I have
that launches an instance of sqlline. Beware that Docker's networking
might be finicky.
https://hub.docker.com/r/joshelser/sqlline/
something like..
`docker pull joshelser/sqlline && docker run -ti joshelser/sqlline
"jdbc:avatica:remote:url=https://cloudapp.azure.com:8443/gateway/sandbox/avatica/;avatica_user=guest;avatica_password=guest-password;authentication=BASIC"`

Subject: Re: Validating Avatica Support with Knox
Hi Ben -
Thanks for reporting this difficulty - I will need to review the docs and
instructions and get back to you.
I am copying Josh on this thread just in case he isn't subscribed - he
contributed the service definition for avatica.
Just to make sure... you have a build from master or 0.11.0 release
deployed in azure that you are trying - right?
thanks,
--larry

Hi,
I work for CGI and have been looking at Knox recently for a project. I've
been working with John McParland who has contributed to Knox with Solr
support.
I'm currently trying to get Knox and Avatica working together. I've
followed the instructions on this JIRA ticket (https://issues.apache.org/
jira/browse/KNOX-844) but I've encountered an error.
When doing the following:
```
$ curl -k -u guest:guest-password -X GET "https://cloudapp.azure.com:
8443/gateway/sandbox/avatica/"
<HTML>
<HEAD>
<TITLE>Error 404 - Not Found</TITLE>
<BODY>
<H2>Error 404 - Not Found.</H2>
No context on this server matched or handled this request.<BR>Contexts

border= 0 src="/favicon.ico"/></a> <a

</BODY>
</HTML>
```
The 404 makes sense since navigating to http://cloudapp.azure.com:8765/
shows the same 404 message.
And looking in the Knox gateway.log file we see Knox has authenticated
fine:
```
2017-02-15 11:20:02,681 INFO hadoop.gateway (KnoxLdapRealm.java:getUserDn(691))
- Computed userDn: uid=guest,ou=people,dc=hadoop,dc=apache,dc=org using
dnTemplate for principal: guest
```
However, when using the Avatica parameters with those semicolons it falls
over:
```
$ curl -k -u guest:guest-password -X GET "https://cloudapp.azure.com:
8443/gateway/sandbox/avatica/;avatica_user=guest;avatica_
password=guest-password;authentication=BASIC"
<html>
<head>

</body>
</html>
```
And the gateway.log now:
```

I believe the important part is:
```
2017-02-15 11:40:18,461 ERROR hadoop.gateway
(UrlRewriteProcessor.java:rewrite(169))
- Failed to rewrite URL: https://hdp24sandbox-v2.
ukwest.cloudapp.azure.com:8443/gateway/sandbox/avatica;
avatica_user=username;avatica_password=password;authentication=BASIC,
direction: IN via rule: AVATICA/avatica/inbound/root, status: FAILURE
```
Which reveals that the URL is not matching the route properly.
I've modified the rewrite.xml file for Avatica in several different ways
but I cannot get Knox to accept semicolons in the URL.
Any help would be appreciated.
Kind regards,
Ben Jovanic
