-------------------------------
Summary: Replacing the implementation of Hive CLI using Beeline (was:
Unify Hive CLI and Beeline)
> Replacing the implementation of Hive CLI using Beeline
> ------------------------------------------------------
>
> Key: HIVE-10511
> URL: https://issues.apache.org/jira/browse/HIVE-10511
> Project: Hive
> Issue Type: Bug
> Components: CLI
> Affects Versions: 0.10.0
> Reporter: Xuefu Zhang
>
> Hive CLI is a legacy tool which had two main use cases:
> 1. a thick client for SQL on hadoop
> 2. a command line tool for HiveServer1.
> HiveServer1 is already deprecated and removed from Hive code base, so use
> case #2 is out of the question. For #1, Beeline provides or is supposed to
> provides equal functionality, yet is implemented differently from Hive CLI.
> As it has been a while that Hive community has been recommending Beeline +
> HS2 configuration, ideally we should deprecating Hive CLI. Because of wide
> use of Hive CLI, we instead propose replacing Hive CLI's implementation with
> Beeline plus embedded HS2 so that Hive community only needs to maintain a
> single code path. In this way, Hive CLI is just an alias to Beeline at either
> shell script level or at high code level. The goal is that no changes or
> minimum changes are expected from existing user scrip using Hive CLI.
> This is an Umbrella JIRA covering all tasks related to this initiative. Over
> the last year or two, Beeline has been improved significantly to match what
> Hive CLI offers. Still, there may still be some gaps or deficiency to be
> discovered and fixed. In the meantime, we also want to make sure the enough
> tests are included and performance impact is identified and addressed.
