Bruno Mahé commented on BIGTOP-852:
-----------------------------------
Right now, as a first pass, I would rather just ensure yarn is setup correctly
so we can unblock BIGOTP-637. We can always open another ticket or discussion
regarding a better long term solution.
To pile on the others suggestions regarding a longer term solution:
* I don't want to have a jenkins user or some fancy magic to detect the current
user. I just want to pass a list of users to that helper script. Maybe it
should be a completely different script if easier.
* I don't want that script to set up all the services. I just want to pass a
list of services to be initialized.
* As Cos suggested, we may want to use some language (groovy wouldn't be my
first choice :p) instead of individual calls to the hadoop command

> Key: BIGTOP-852
> URL: https://issues.apache.org/jira/browse/BIGTOP-852
> Project: Bigtop
> Issue Type: Bug
> 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.
