Subject [jira] [Commented] (HIVE-13670) Improve Beeline connect/reconnect semantics
Date Mon, 09 May 2016 21:51:12 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13670?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15277112#comment-15277112

Thejas M Nair commented on HIVE-13670:
--------------------------------------

In Beeline.java
how about initing the url 'if (cl.hasOption("reconnect"))' instead of duplicating the code
that is under 'if (url != null) {' ?


> Improve Beeline connect/reconnect semantics

> 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)
