Allow DATABASE_URL to be provided

[naude-r]

would it be possible to allow an optional DATABASE_URL to be provide? this is mostly to configure jdbc url that differs slightly from the norm, e.g. mssql:
jdbc:sqlserver://localhost:1433;DatabaseName=hive_metastore;

using the existing env variables result in an error:
Underlying cause: com.microsoft.sqlserver.jdbc.SQLServerException : The port number 1433/hive_metastore is not valid.

if DATABASE_URL is specified then the other connection related env can be skipped.

Apologies for the very long delay; from your post it's evident you're trying to use MS-SQL with HMS; however, that's may break for more than just the connection url because the image is only configuring the Postgres driver. Got a couple questions for you

1. Did support an optional DATABASE_URL env variable. #9 make the image work with MS-SQL server?
2. Are you still interested in seeing this issue resolved?

@naushadh thank you for the response. yes, the PR did solve the issue.

unfortunately we've since moved on to other solutions and do not require this anymore.

Understandable; just for curiosity, do you mind sharing the other solution that you'd moved to?

sure, the client moved to a cloud managed instance.
