             Summary: Preserve log directory and container name even when task.opts is overwritten
                 Key: SAMZA-345
                 URL: https://issues.apache.org/jira/browse/SAMZA-345
             Project: Samza
          Issue Type: Bug
          Components: container
    Affects Versions: 0.8.0
            Reporter: Chinmay Soman


Currently, when the user customizes task.opts, the default settings are overwritten, which means - we also lose $SAMZA_LOG_DIR and $SAMZA_CONTAINER_NAME. 

This is discussed in detail in SAMZA-109

The initial recommendation is to do the following things

1. Add CommandBuilder.setLogDir.
2. Make ShellCommandBuilder.buildEnvironment do a string replace for task.opts (ENV_JAVA_OPTS) to replace $SAMZA_LOG_DIR with log dir, and $SAMZA_CONTAINER_NAME with container name.
3. Update SamzaAppMasterTaskManager, and ProcessJobFactory to use the new CommandBuilder.setLogDir method.
