Arpit Gupta reassigned YARN-673: -------------------------------- Assignee: Arpit Gupta > Remove yarn-default.xml > ----------------------- > > Key: YARN-673 > URL: https://issues.apache.org/jira/browse/YARN-673 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Siddharth Seth > Assignee: Arpit Gupta > > The default configuration files serve 2 purposes > 1. Documenting available config parameters, and their default values. > 2. Specifying default values for these parameters. > An xml file hidden inside a jar is not necessarily the best way to document > parameters. This could be moved into the documentation itself. > Default values already exist in code for most parameters. There's no need to > specify them in two places. We need to make sure defaults exist for all > parameters before attempting this. > Having default configuration files just bloats job conf files; over 450 > parameters, out of which <20 are likely job specific params. JobConf files > end up being rather big, and the memory footprint of the conf object is large > (>300KB last I checked). -- This message is automatically generated by JIRA.
