- workaround about the security HDFS with insecurity DynoYarn container to download simulatedFatJar.
- unset APPLICATION_WEB_PROXY_BASE to display RM normally.
- change /grid to $base/tmp due to /grid may not exist.
Original plan is that generator app need to upload simulatedFatJat to HDFS, and then download the simulatdFatJar from HDFS when it runs simulated container. However, dyno yarn cluster is unsecurity, the cluster use simple auth. Therefore, the simulated container which use simple auth can never download the file from HDFS which use kerberos auth. When driver app runs, it could download all necessary files, and put the file in a centain path. Meanwhile, generator app add that path into CLASSPATH. Then we can avoid above situation.
