Description

During container launch the environment variables may get expanded in random order. So if you define a variable such as AGENT_LOG_ROOT = %LOG_DIRS% then it may not expand correctly if LOG_DIRS is expanded later. For example:

@set AGENT_LOG_ROOT=%LOG_DIRS%
....
@set LOG_DIRS=c:/hadoop/data/hadoop/logs/application_1411325548120_0018/container_1411325548120_0018_01_000010

Instead, the code should directly use the existing environment variables.
