> In Windows environment, environment variable is quoted to preserve special characters like space. However since MapredLocalTask will call hadoop.cmd to launch ExecDriver and hadoop.cmd will reconstruct environment variable like 
> {code}
> set HADOOP_OPTS=%HADOOP_OPTS% %HADOOP_CLIENT_OPTS%
> {code}
> the quotes for HADOOP_CLIENT_OPTS will be part of HADOOP_OPTS and nullify the variables in HADOOP_CLIENT_OPTS after appending to HADOOP_OPTS. 
> Example HADOOP_OPTS:
> {code}
> -Dhadoop.log.dir=C:\apps\dist\hadoop-1.2.0.1.3.1.0-06\logs -Dhadoop.log.file=hadoop.log -Dhadoop.home.dir=C:\apps\dist\hadoop-1.2.0.1.3.1.0-06 -Dhadoop.root.logger="INFO,TLA" -Djava.library.path=;C:\apps\dist\hadoop-1.2.0.1.3.1.0-06\lib\native\Windows_NT-amd64-64;C:\apps\dist\hadoop-1.2.0.1.3.1.0-06\lib\native -Dhadoop.policy.file=hadoop-policy.xml "-Dhadoop.tasklog.taskid=attempt_201310092133_0006_m_000000_0 -Dhadoop.tasklog.iscleanup=false -Dhadoop.tasklog.totalLogFileSize=0" 
> {code}
> One failure scenario is when map side join is launched by Oozie, the job fails because cannot find "hadoop.tasklog.taskid" and throw exception when initializing log4j
