Siddharth Seth created YARN-2464: ------------------------------------ Summary: Provide Hadoop as a local resource (on HDFS) which can be used by other projcets Key: YARN-2464 URL: https://issues.apache.org/jira/browse/YARN-2464 Project: Hadoop YARN Issue Type: Improvement Reporter: Siddharth Seth
DEFAULT_YARN_APPLICATION_CLASSPATH are used by YARN projects to setup their AM / task classpaths if they have a dependency on Hadoop libraries. It'll be useful to provide similar access to a Hadoop tarball (Hadoop libs, native libraries) etc, which could be used instead - for applications which do not want to rely upon Hadoop versions from a cluster node. This would also require functionality to update the classpath/env for the apps based on the structure of the tar. As an example, MR has support for a full tar (for rolling upgrades). Similarly, Tez ships hadoop libraries along with it's build. I'm not sure about the Spark / Storm / HBase model for this - but using a common copy instead of everyone localizing Hadoop libraries would be useful. -- This message was sent by Atlassian JIRA (v6.2#6252)
