> Key: HIVE-16558
> URL: https://issues.apache.org/jira/browse/HIVE-16558
> Project: Hive
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: ZhangBing Lin
> Assignee: ZhangBing Lin
> Attachments: HIVE-16558.1.patch, HIVE-16558.2.patch
>
>
> In QueryProfileImpl.jamon,We see the following settings：
> <?xml version="1.0" encoding="UTF-8" ?>
> <html lang="en">
> <head>
> <meta charset="utf-8">
> <title>HiveServer2</title>
> <meta name="viewport" content="width=device-width, initial-scale=1.0">
> <meta name="description" content="">
> <link href="/static/css/bootstrap.min.css" rel="stylesheet">
> <link href="/static/css/bootstrap-theme.min.css" rel="stylesheet">
> <link href="/static/css/hive.css" rel="stylesheet">
> </head>
> So we should set the response code to utf-8, which can avoid Chinese garbled
> or other languages garbled,Please check it!
> This patch can only solve Drilldown read data from the cache when the
> Chinese show abnormal, and can not solve the Explain plan from the database
> query Chinese garbled, because the Chinese stored in the database is garbled.
> If you want to solve this problem, you need to modify the database
> encoding format.
> I try to modify the mysql 'columns_v2' table field 'comment' encoding
> utf8，Is this okay？
