------------------------------------
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.
