Description

用 superset  链接impala 视图查询，打开看板偶尔会报如图3的的错，都是在解析SQL时找不到内置函数的错，但是强制刷新看板重新查询又不再报错，连续多次查询都会报，但是过一会再强制刷新查询又会报错，前后查询SQL语句一致，见图1和图2，日志见附件文档，能不能帮忙提一下意见是哪方面bug 

Adding the Google-translated English version (laszlog):
Use the superset to link the impala view query. When you open the kanban board, you will occasionally report the error as shown in Figure 3. It is the error that you cannot find the built-in function when parsing the SQL. However, after a while, you will be forced to refresh the query again and you will get an error. The query SQL statement is consistent before and after, see Figure 1 and Figure 2, the log is in the attached document, can you help to mention what is the bug?
