Philip Zeyliger commented on IMPALA-8025: ----------------------------------------- {{run-tests.py}} is a wrapper around {{py.test}}. It's likely you can run the test directly with {{impala-py.test tests/metadata/test_explain.py -vv -s}} and get a bit more of what you want. If we want to always pass {{-vv}} to py.test, the invocation is at and around https://github.com/apache/impala/blob/master/tests/run-tests.py#L294 . > End-to-end tests sometimes unhelpfully truncate error output > ------------------------------------------------------------ > > Key: IMPALA-8025 > URL: https://issues.apache.org/jira/browse/IMPALA-8025 > Project: IMPALA > Issue Type: Bug > Components: Infrastructure > Affects Versions: Impala 3.1.0 > Reporter: Paul Rogers > Priority: Minor > > Made a change to the DESCRIBE output per IMPALA-8021. This required > adjustment to {{metadata/test_explain.py}} to account for the change. The > test encodes a "golden" version in a .test file using a specialized syntax. > But, when running the test, the output shows the first few lines (which do > match), then elides the rest: > {noformat} > E row_regex:.*mem-estimate=[0-9.]*[A-Z]*B mem-reservation=[0-9.]*[A-Z]*B > thread-reservation=0 == '| mem-estimate=0B mem-reservation=0B > thread-reservation=0' > E Detailed information truncated (45 more lines), use "-vv" to show > {noformat} > As it turns out, passing "-vv" to {{tests/run-tests.py}} does not seem to > pass it to the test program, so that did not work. > The .xml file for the test contains the same message: output is truncated. > Same in the .log file. > So, the question is, how is a developer to figure out the issue if we can't > see the actual error lines? This is the kind of thing that converts a simple > task into a multi-hour ordeal. > Right now, the only solution is to rerun the tests with {{--update_results}} > flag to {{run-tests.py}}, then hunt down the generated output file. > Better would be to output the n lines before the error, rather than the first > n lines. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
