Benjamin Teke updated YARN-10422: --------------------------------- Attachment: YARN-10422.POC.003.patch > Create the script responsible for collecting the bundle data > ------------------------------------------------------------ > > Key: YARN-10422 > URL: https://issues.apache.org/jira/browse/YARN-10422 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Benjamin Teke > Assignee: Benjamin Teke > Priority: Major > Attachments: YARN-10422.POC.001.patch, YARN-10422.POC.002.patch, > YARN-10422.POC.003.patch > > > The script should provide the list of diagnostic use-cases described in > YARN-10421. If a request comes in to the YarnDiagnosticCollector servlet, the > script will be invoked. It collects all the information required for that > diagnostic category and saves it into a configurable directory as a > compressed tar file. > An example of how the script could look like: > {code:java} > if [$1 = "listcommonissues"] > echo "1, Application Failed" > echo "2, Application Hanging" > echo "3, Scheduler Related Issue" > echo "4, RM failure to start" > echo "5, NM failure to start" > elif [$1 = "collect"] > if [$2 == 1] > appId = $3 > mkdir /tmp/$appId > yarn logs -applicationId $appId > /tmp/$appId/joblogs > curl <JHS>/{appId}/conf > /tmp/$appId/conf > curl <RM>/logs | grep container > /tmp/$appId/rmlogs > curl <NM>/logs | grep container > /tmp/$appId/nmlogs > outputpath = /tmp/$appId > elif ... > elif ... > fi tar and compress outputpath.{code} > > During class load YarnDiagnosticsCollector reads the list of common issues > from the script and keeps it in memory. On every startup of YARN UI2 > diagnostics page, it fetches the list from the servlet and displays them. The > servlet should handle the script changes, so if a new diagnostic case is > added, a YARN UI2 reload should show it. This way the users can easily plug > new categories without any UI2 or Servlet code change. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
