-------------------------------------
[~analog.sony] Sorry about the delay in reviewing this.
This patch does not consider
"hive2://abcd.com:10000;principal=hive/hiveserver2h...@your-realm.com" as an
invalid path.
I think the better check is to check that the authority portion is not empty
and host portion is null .
To illustrate how the parsing happens for above jdbc uri -
{code}
String ustr
= "hive2://abcd.com:10000;principal=hive/hiveserver2h...@your-realm.com";
URI uri = URI.create(ustr);
System.out.println("uri " + uri);
System.out.println("auth " + uri.getAuthority());
System.out.println("uinfo " + uri.getUserInfo());
System.out.println("host " + uri.getHost());
System.out.println("path " + uri.getPath());
{code}
has the following output -
{code}
uri hive2://abcd.com:10000;principal=hive/hiveserver2h...@your-realm.com
auth abcd.com:10000;principal=hive
uinfo null
host null
path /hiveserver2h...@your-realm.com
{code}
> Missing "/" or "/<dbname>" in hs2 jdbc uri switches mode to embedded mode

>
> When the jdbc uri does not have a / or "/default" after the hostname:port,
> and the principal is specified, it ends up launching HS2 in embedded mode.
> This is because the parsing of uri in such case does not end up extracting
> the hostname.
> eg . "jdbc:hive2://<host>:<port>;principal=<>." results HS2 embedded mode
> getting used.
> "jdbc:hive2://<host>:<port>/;principal=<>" or
> "jdbc:hive2://<host>:<port>/default;principal=<>" results in it connecting to
> the standalone hive server 2.
