Steve Loughran created YARN-1565: ------------------------------------ Summary: Add a way for YARN clients to get critical YARN system properties from the RM Key: YARN-1565 URL: https://issues.apache.org/jira/browse/YARN-1565 Project: Hadoop YARN Issue Type: Improvement Components: resourcemanager Affects Versions: 2.2.0 Reporter: Steve Loughran
If you are trying to build up an AM request, you need to know # the limits of memory, core &c for the chosen queue # the existing YARN classpath # the path separator for the target platform (so your classpath comes out right) # cluster OS: in case you need some OS-specific changes The classpath can be in yarn-site.xml, but a remote client may not have that. The site-xml file doesn't list Queue resource limits, cluster OS or the path separator. A way to query the RM for these values would make it easier for YARN clients to build up AM submissions with less guesswork and client-side config. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
