Sangjin Lee created MAPREDUCE-5232: -------------------------------------- Summary: log classpath and other key properties on child JVM start Key: MAPREDUCE-5232 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5232 Project: Hadoop Map/Reduce Issue Type: Improvement Components: mrv1, mrv2 Affects Versions: 2.0.4-alpha Reporter: Sangjin Lee
It would be great if we log vital information such as classpath, etc. upon a mapreduce child JVM start. This would help a great deal in terms of troubleshooting classpath issues, etc. Today it is pretty difficult to debug this unless you preserve the container script. Maybe it can log things like classpath, os name/version, java version, etc. at the beginning of the child JVM start. -- This message is automatically generated by JIRA.
