Flink SQL SET 语句在 CLI 中不起作用

Question

我正在使用 Flink SQL 客户端（Flink 版本 1.13.1）提交我的作业，但是，文档中提到的 SET 语句（https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/dev/table/sql/overview/）给了我解析错误，尝试使用 -i em> 文件选项。

命令：./bin/sql-client.sh 嵌入 -f /tmp/test.sql

错误：

    Flink SQL> -- DEBUGGING
SET 'sql-client.verbose' = 'true';
[ERROR] Could not execute SQL statement. Reason:
org.apache.flink.sql.parser.impl.ParseException: Encountered "\'sql-client.verbose\'" at line 2, column 5.
Was expecting one of:
    <BRACKET_QUOTED_IDENTIFIER> ...
    <QUOTED_IDENTIFIER> ...
    <BACK_QUOTED_IDENTIFIER> ...
    <HYPHENATED_IDENTIFIER> ...
    <IDENTIFIER> ...
    <UNICODE_QUOTED_IDENTIFIER> ...


Shutting down the session...
done.

看起来你在 SQL 客户端复制多行，所以复制如下：

--DEBUGGING
SET 'sql-client.verbose' = 'true';

SQL 客户端当前不支持此功能。如果删除注释行，您将看到设置已正确执行：

Flink SQL> SET 'sql-client.verbose' = 'true';
[INFO] Session property has been set.
