Description

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.
