The collaboration with SIMBA for the HDP ODBC driver ensures it gets the same
wins as the open source JDBC one, so that Excel, Microstrategy and Tableau can
see the gains.
The concerns for beeline are somewhat inherited from sqlline mostly related to
formatting performance. The raw JDBC protocol is usually ~10x faster to
transport data over 10GigE than beeline can print.
If this is a hard concern, I recommend commenting or interacting with those
specific collaboration JIRAs.
> 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
> Assignee: Ferdinand Xu
>
> 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.
