-------------------------------------
[~zhangbutao] [~abstractdog]
hello. Do you think we need to improve the documentation on LLAP?At the moment
it doesn't seem to be able to guide users on how to use LLAP.
> The Hive LLAP documentation on ASF Confluence appears to be out of date
> -----------------------------------------------------------------------
>
> Key: HIVE-28645
> URL: https://issues.apache.org/jira/browse/HIVE-28645
> Project: Hive
> Issue Type: Improvement
> Security Level: Public(Viewable by anyone)
> Reporter: Qiheng He
> Priority: Major
>
> - The documentation for Hive LLAP on ASF Confluence looks outdated or not
> intuitive enough? I mean
> [https://cwiki.apache.org/confluence/display/Hive/LLAP] .
> - This document directs the configuration of LLAP to
> [https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-LLAP]
> . But the document never states the minimum configuration to enable LLAP.
> LLAP does not seem to be enabled by default.
> - [https://cwiki.apache.org/confluence/display/Hive/LLAP] also mentions that
> LLAP is deployed as *SLIDER* on {*}YARN Deployment{*}. But *Apache Slider* is
> actually archived. See [https://github.com/apache/incubator-retired-slider] .
> Does this mean that Hive support for LLAP is outdated?
> - [https://cwiki.apache.org/confluence/display/Hive/LLAP] also mentions that
> the LLAP Web UI is available at *localhost:15002* . But the self-description
> text of Hive's Docker Image never mentions that port *15002* can be exposed.
> See [https://hub.docker.com/r/apache/hive] . Port *15002* does not belong to
> {*}HiveServer2 or Hive Metastore{*}?
> - I have to wonder about the current minimum configuration of Hive to start
> LLAP.
