Sushanth Sowmyan updated HIVE-13670:
------------------------------------
Resolution: Fixed
Fix Version/s: 2.1.0
Release Note:
Couple of usability changes to beeline:
a) reconnect semantics: !reconnect will re-connect using the same last used
connect url after doing a !close. In addition, if you do a !save after
connecting, then that url is recoreded in beeline.properties, and can be
referred to in any future session, simply by running !reconnect in the beeline
shell, or by running beeline as beeline -r.
b) named connect strings using env variables : Now, !connect as well as beeline
-u can take non-url parameters which are assumed to be the name of a
cluster/etc, as follows. If there is a env variable called
BEELINE_URL_BLUE=<jdbc url>, then specifying "!connect blue" or "beeline -u
blue" will pick that up and use that appropriate jdbc url. A suggested use for
cluster admins will probably be to define something like a BEELINE_URL_DEFAULT
and recommend that users use a "beeline -u default"
Status: Resolved (was: Patch Available)
Committed to master.

> For most users of beeline, chances are that they will be using it with a
> single HS2 instance most of the time. In this scenario, having them type out
> a jdbc uri for HS2 every single time to !connect can get tiresome. Thus, we
> should improve semantics so that if a user does a successful !connect, then
> we must store the last-connected-to-url, so that if they do a !close, and
> then a !reconnect, then !reconnect should attempt to connect to the last
> successfully used url.
> Also, if they then do a !save, then that last-successfully-used url must be
> saved, so that in subsequent sessions, they can simply do !reconnect rather
> than specifying a url for !connect.
> In addition, it would be useful to introduce a new way of doing !connect that
> does involve typing out a jdbc url every time (since this is highly likely to
> be error-prone)
