HbaseUI>Table Details not accessible from Knox endpoint intermittently

This is due to the SSO logic that checks for originalURL query param.

During the first login, this is the redirect URL:

https://local.site/gateway/knoxsso/api/v1/websso?originalUrl=https://local.site/gateway/proxy/hbase/webui/master?host=local.site&port=16010

When this reaches WebSSOResource.getOriginalUrlFromQueryParams() functionvalue of request.getParameter(ORIGINAL_URL_REQUEST_PARAM) is

https://local.site/gateway/proxy/hbase/webui/master?host=local.site
Note: port information is missing. This is because of the & query param which treats port as a separate param and not part of original URL.

Also, because of the same reason '?' is added after the host, this is where it is done

This is why additional ? gets added.
