Bruno Mahé commented on BIGTOP-852:
-----------------------------------
{quote}I think the question here is performance: shell is as good language as
Python. But non of them can work with Java APIs of the Hadoop. Hence, the
choice.{quote}
I am also suggesting to use something other than bash for performance reason.
No disagreement there.
But groovy would still not be my choice and there are other jvm based
languages. The language to use does not matter and I will let whoever resolves
that ticket pick whatever language (s)he wants as long as the performance
improve overall.
> Improve HDFS helper script
> --------------------------

> Key: BIGTOP-852
> URL: https://issues.apache.org/jira/browse/BIGTOP-852
> Project: Bigtop
> Issue Type: Sub-task
> Components: Deployment
> Affects Versions: 0.6.0
> Reporter: Mark Grover
> Fix For: 0.6.0
>
>
> 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.
