Sangjin Lee updated MAPREDUCE-5232: ----------------------------------- Attachment: MAPREDUCE-5232-branch-2.patch > 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 > Assignee: Sangjin Lee > Attachments: MAPREDUCE-5232-branch-2.patch, > MAPREDUCE-5232-branch-2.patch, MAPREDUCE-5232-branch-2.patch, > MAPREDUCE-5232.patch, MAPREDUCE-5232.patch, MAPREDUCE-5232.patch > > > 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.
