Jason Lowe created YARN-2369: -------------------------------- Summary: 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
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 (v6.2#6252)
