Jason Lowe commented on YARN-2369: ---------------------------------- Sure, feel free to post a proposed design/patch for it. > Environment variable handling assumes values should be appended > --------------------------------------------------------------- > > Key: YARN-2369 > URL: https://issues.apache.org/jira/browse/YARN-2369 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 2.2.0 > Reporter: Jason Lowe > Assignee: Dustin Cote > > When processing environment variables for a container context the code > assumes that the value should be appended to any pre-existing value in the > environment. This may be desired behavior for handling path-like environment > variables such as PATH, LD_LIBRARY_PATH, CLASSPATH, etc. but it is a > non-intuitive and harmful way to handle any variable that does not have > path-like semantics. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
