Gera Shegalov commented on YARN-2934: ------------------------------------- -1 on manual regexes in favor of code reuse. 99.9% of YARN users will never change this conf. Simple globs I was suggesting already cover even AppMaster.stderr. In ContainerLaunch#getErrorLogTail get rid of {code} if (containerLogDir == null) { return null; } {code} it cannot be null > Improve handling of container's stderr > --------------------------------------- > > Key: YARN-2934 > URL: https://issues.apache.org/jira/browse/YARN-2934 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Gera Shegalov > Assignee: Naganarasimha G R > Priority: Critical > Attachments: YARN-2934.v1.001.patch, YARN-2934.v1.002.patch, > YARN-2934.v1.003.patch, YARN-2934.v1.004.patch, YARN-2934.v1.005.patch, > YARN-2934.v1.006.patch, YARN-2934.v1.007.patch > > > Most YARN applications redirect stderr to some file.
