Gabor Kaszab commented on IMPALA-13067:
---------------------------------------

No, there has been no work done on this one. Another Iceberg test related issue 
was mentioning this, but this is more general for the test framework.

> Some regex make the tests unconditionally pass

> This issue came out in the Iceberg metadata table tests where this regex was 
> used:
> [1-9]\d*|0
>  
> The "|0" part for some reason made the test framework confused and then 
> regardless of what you provide as an expected result the tests passed. One 
> workaround was to put the regex expression between parentheses. Or simply use 
> "d+". https://issues.apache.org/jira/browse/IMPALA-13055 applied this second 
> workaround on the tests.
> Some analysis would be great why this is the behavior of the test framework, 
> and if it's indeed the issue of the framnework, we should fix it.
