Alejandro Abdelnur moved MAPREDUCE-5111 to YARN-538: ---------------------------------------------------- Component/s: (was: jobhistoryserver) Affects Version/s: (was: 2.0.3-alpha) 2.0.3-alpha Key: YARN-538 (was: MAPREDUCE-5111) Project: Hadoop YARN (was: Hadoop Map/Reduce) > RM address DNS lookup can cause unnecessary slowness on every JHS page load > ---------------------------------------------------------------------------- > > Key: YARN-538 > URL: https://issues.apache.org/jira/browse/YARN-538 > Project: Hadoop YARN > Issue Type: Improvement > Affects Versions: 2.0.3-alpha > Reporter: Sandy Ryza > Assignee: Sandy Ryza > Attachments: MAPREDUCE-5111.patch > > > When I run the job history server locally, every page load takes in the 10s > of seconds. I profiled the process and discovered that all the extra time > was spent inside YarnConfiguration#getRMWebAppURL, trying to resolve 0.0.0.0 > to a hostname. When I changed my yarn.resourcemanager.address to localhost, > the page load times decreased drastically. > There's no that we need to perform this resolution on every page load. -- This message is automatically generated by JIRA.
