Steve Loughran commented on YARN-1565: -------------------------------------- -ignore the yarn config one. like you say: not a new problem. And no, no findbugs errors listed. > 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 > Attachments: YARN-1565-001.patch, YARN-1565-002.patch, > YARN-1565-003.patch > > > 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 (v6.3.4#6332)
