LoggingResearch commented on MAPREDUCE-7488: -------------------------------------------- To make it clear on how to fix the issue, we upload the comparison between the original version and the log-enhanced version in the attached file `original-vs-log-enhanced.md`. The log-enhanced version is generated automatically utilizing our proposed tool. > Missing System Output for Misconfiguration in Local Mode Settings > ----------------------------------------------------------------- > > Key: MAPREDUCE-7488 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-7488 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: mapreduce-client > Affects Versions: 3.3.6 > Environment: Version: {{`3.3.6`}} > Location: > {{{}`hadoop/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-common/src/main/java/org/apache/hadoop/mapred/LocalClientProtocolProvider.java`{}}}, > in {{`create`}} method, from Line 37 - 39. > Reporter: LoggingResearch > Priority: Major > Attachments: LocalClientProtocolProviderTest.java, > original-vs-log-enhanced.md > > > Enabling {{local mode}} in {{mapreduce}} requires setting the > {{mapreduce.framework.name}} configuration parameter to {{{}local{}}}. > However, users who are unfamiliar with configuration parameters may struggle > to do this correctly. The system currently lacks runtime output indicating > whether this configuration has taken effect, leading to confusion and a > higher likelihood of misconfiguration. > > *Expected Behavior:* > If the system fails to activate the {{LocalJobRunner}} because the > {{mapreduce.framework.name}} parameter is not set to {{{}local{}}}, a warning > should be output to notify the user. > > *How-to-Fix:* > We propose enhancing system observability and diagnosability by adding > logging. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
