Steve Loughran commented on HADOOP-7092:
----------------------------------------
I'm going to ask something more subversive: why are we using Bash?
Could we say "use python" for the scripts. It's a better language from a
maintenance perspective, because it is closer to the java language that most
developers in the Hadoop stack will have encountered. On a windows system, it
will add one place that Cygwin is not needed.
It would also offer a more powerful base set of functions in the python runtime
-things that won't need team maintenance (and the delays to trickle down to
other project/cost of maintaining forks).
I'd be tempted to try writing some .py versions of the basic script if anyone
else was interested.

> Key: HADOOP-7092
> URL: https://issues.apache.org/jira/browse/HADOOP-7092
> Project: Hadoop Common
> Issue Type: Task
> Components: scripts
> Reporter: Thomas Koch
> Priority: Minor
>
> - Today we struggled ~1-2 hours to find out that the Cloudera init scripts
> have a bug in the shell code (bug filled by my colleague)
> - Many projects that started at hadoop copied and adapted the shell startup
> code. So there's a lot of code duplication between hbase, zookeeper, hadoop
> and maybe others
> - There already are some open issues regarding to shell code
> - The shell code isn't properly tested (automaticaly) and will first probably
> fail at customer side
> Would it make sense to build a shell library of most often used functionality
> for startup scripts? Is there already such a library somewhere?
> This issue should collect thoughts in this area.
