[jira] [Commented] (YARN-3670) Add JobConf XML link in Yarn RM UI
[ https://issues.apache.org/jira/browse/YARN-3670?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14548020#comment-14548020 ] Jason Lowe commented on YARN-3670: -- This is not easily implementable in the general case, since not all YARN applications have a job conf that is an XML file and accessible via a link. While this is true for MapReduce jobs, YARN is not MapReduce-specific. This is similar to asking for the number of maps and reduces to be available on the RM UI. > Add JobConf XML link in Yarn RM UI > -- > > Key: YARN-3670 > URL: https://issues.apache.org/jira/browse/YARN-3670 > Project: Hadoop YARN > Issue Type: Improvement > Components: webapp >Affects Versions: 2.6.0 > Environment: HDP 2.2 >Reporter: Hari Sekhon >Priority: Minor > > Request to add JobConf xml link for each application in the RM UI so I don't > have to keep recovering it from HDFS to debug if job settings are taking > effect. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

At the moment it's too opaque, which is a first generation side-effect of Yarn being a generally abstracting resource manager. However, perhaps it would be possible to create a generic mechanism that allows jobs to publish key-value pairs which could be populated with either settings or counters to be displayed via a new named link also specified per set of key-value pairs, such as a job could publish "counters" or "configuration". In this way both the MapReduce client, the Tez client and any other YARN apps would have the ability to publish any arbitrary key-value pair table of information to YARN to display in the UI? This would help immensely with debugging yarn jobs. > Add JobConf XML link in Yarn RM UI > -- > > Key: YARN-3670 > URL: https://issues.apache.org/jira/browse/YARN-3670 > Project: Hadoop YARN > Issue Type: Improvement > Components: webapp >Affects Versions: 2.6.0 > Environment: HDP 2.2 >Reporter: Hari Sekhon >Priority: Minor > > Request to add JobConf xml link for each application in the RM UI so I don't > have to keep recovering it from HDFS to debug if job settings are taking > effect. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

However this is far from a "minor" improvement and could be quite involved, including questions like where will these settings be stored (probably timelineserver), limits on the key/value sizes, limits on total amount of data that can be stored, etc. > Add JobConf XML link in Yarn RM UI > -- > > Key: YARN-3670 > URL: https://issues.apache.org/jira/browse/YARN-3670 > Project: Hadoop YARN > Issue Type: Improvement > Components: webapp >Affects Versions: 2.6.0 > Environment: HDP 2.2 >Reporter: Hari Sekhon >Priority: Minor > > Request to add JobConf xml link for each application in the RM UI so I don't > have to keep recovering it from HDFS to debug if job settings are taking > effect. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
