> There are a few things that can be improved regarding the HDFS helper script introduced by BIGTOP-547. Some of these issues have been discussed in BIGTOP-637.
> 1. The script seems to create user directories for users "root" and "jenkins" but not the current user running the script. I think it will be a good idea to add in the script the commands to create the /user/$USER directory in HDFS. Of course, we should be careful in case the user running the command is root or jenkins, in that case a simple mkdir command would throw error given that those directories already exist.
> 2. The script uses sudo which requires login shell. However, login shells are not available for certain use cases like init scripts. Consequently, we should consider using su instead.
> 3. Look into how the helper script can be made faster
> Folks, please feel free to add/edit if there is something I missed.
