[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
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.
