> Hadoop-3854 introduced a framework where users can add filters to the HTTP server to filter part of the HTTP interface, i.e., those user facing URLs. Directories "/logs/*" and "/static/*" are supposed to be filtered. However, files in those directories can be retrieved without triggering my configured filter. The corresponding junit test didn't catch the bug for 2 reasons. 1) it didn't try to access files in those 2 directories. 2) Even if it did, it might still fail to catch the bug, since according to my observation, only when accessing existent files my filter is bypassed. When accessing non-existent files (which is what the junit test does), my filter is triggered as expected.
