@xunliu what is the purpose of adding this extension? My thinking is that if we run the ITs using gradle, then there'll be so many log output for each test. This is helpful for debugging one IT on idea, but seems not so useful when we run all the ITs using gradle. WDYT?

Yeah, this is very useful when developing Gravitino locally, especially for those who are not familiar with it. They may encounter unexpected issues while debugging integration tests.

[jerryshao]

I think we already output such information in the idea output, as I just confirmed with @yuqi1129 offline.

@xunliu , I believe you can add this line to show the root cause of why we can't run this test.
