             Summary: Change log dir and container name defaults in run-class.sh
                 Key: SAMZA-75
                 URL: https://issues.apache.org/jira/browse/SAMZA-75
             Project: Samza
          Issue Type: Bug
          Components: container
    Affects Versions: 0.6.0
            Reporter: Chris Riccomini
            Assignee: Chris Riccomini
             Fix For: 0.7.0


Samza uses a run-class.sh script to execute all of its code. The run-class.sh script sets default for two Samza-related environment variables:

SAMZA_LOG_DIR
SAMZA_CONTAINER_NAME

The current defaults are:

SAMZA_LOG_DIR=/tmp
SAMZA_CONTAINER_NAME= # not defined

I propose that we change the log dir default to $base_dir, and the container name default to "undefined-samza-container-name".

The reason I want to do this is that there are cases where these defaults are used, and having an undefined container name leads to a log4j.xml file called ".log" because we're using ${samza.container.name}.log as the file name for log4j rolling file appenders. The reason for the log dir change is that it doesn't make sense to assume that /tmp exists (and is writable, and a sane place to put it, with enough space), and it'd be better to put the log folder somewhere relative to the job package.
