------------------------------
Summary: Improve logging for Samza
Key: SAMZA-954
URL: https://issues.apache.org/jira/browse/SAMZA-954
Project: Samza
Issue Type: Bug
Reporter: Jagadish
Assignee: Jagadish
Often Samza jobs keep running for days (and in our case months). Often log
messages generated by the job get rolled over. A lot of information that is
critical for debugging a job (like the jmx server port, URL, job model for the
current container, configuration that was passed to the container) is often
printed when the job starts. However, since logs get rolled over (by Yarn/ by
sys-administrators) when they exceed a certain size, this information is lost.
This JIRA is to add a separate samza-container-$containerID-startup.log file
with each container. This will have information useful for debugging the job.
