Allen Wittenauer commented on HADOOP-2861:
------------------------------------------
I'd love for the syntax to support
hod allocate --nodecount 30 --clusterdir mydir ...
in addition to realistic single letter options. [How does -z mean deallocate
on exit? If -D is always required, why is it uppercase? ]
Supporting words/phrases instead of single charaters would really help out new
folks to hod as well as making scripts utilizing hod much more supportable.
> [HOD] Improve the user interface for the HOD commands

> Key: HADOOP-2861
> URL: https://issues.apache.org/jira/browse/HADOOP-2861
> Project: Hadoop Core
> Issue Type: Improvement
> Components: contrib/hod
> Affects Versions: 0.16.0
> Reporter: Hemanth Yamijala
> Fix For: 0.16.1
>
>
> The current command line for HOD is not user-friendly or conventional.
> Following improvements are required:
> - We shouldn't require the quotes around the operation.
> - Can we define a HOD_CLUSTER_DIR environment variable which would be used by
> default ?
> With these two, one can imagine a very simple command line for HOD. Something
> like:
> hod-allocate 3
> hod-deallocate
> hod-allocate 3 ~/hod-clusters/test
> hod-deallocate ~/hod-clusters/test
> This would also be backward compatible for people who're used to the current
> model.
