Patch Set 5: (9 comments) Since we're accepting user input it would be great to have unit tests. Checking that the correct logging level is actually in effect might be a little tricky. I'm more thinking along the lines of checking garbage user input, checking that settings are reflected and can be reset, etc. Basic validation. I think you should be able to do something similar to webserver-test.cc. http://gerrit.cloudera.org:8080/#/c/5792/5/be/src/util/backend-gflag-util.h File be/src/util/backend-gflag-util.h: Line 27: /// debugging, so we save the original value here incase we need to restore in case (two words) http://gerrit.cloudera.org:8080/#/c/5792/5/be/src/util/logging-support.cc File be/src/util/logging-support.cc: Line 77: jclass log4j_logger_class_; no "_" suffix since not private class members; make these static Line 196: if (args.find("get_java_log") != args.end()) { make these strings constants like: static const char* GET_JAVA_LOG = "get_java_log"; etc. Line 212: logging_level == args.end() || logging_level->second == NULL) return; use {} for multi-line ifs http://gerrit.cloudera.org:8080/#/c/5792/5/be/src/util/logging-support.h File be/src/util/logging-support.h: Line 25: namespace rapidjson { Ok to use the include if you prefer that solution.
