This looks nice Nicolas.  Want to take care of the few below and I'll then commit?


    Why is it called local-master-backup?  Should be a more descriptive name?  Its the 'backup'
that throws me off.  'local-masters'?


    Explain 'offset' in this usage output?  (Seems to be port offset from default?)


    Isn't the master default port 60000, not 60020?  60020 is RS default port?


    This is commented out because dfs.support.append doesn't work with local fs?


    You are adding a tab here?  Or white-space?


    Add more comment in here... in particular on the '-splitting' suffix.  Where's that come




    There is whitespace in here.


    Sorry Nicolas... this looks like an old unused option.  Should probably remove it.


    This is a nice addition.


    White space

>       true: fully-distributed with unmanaged Zookeeper Quorum (see hbase-env.sh)
>     </description>
>   </property>
> {code}
> running HBase in pseudo destr mode become not so easy, I think description for false
variant is wrong and you can't get pseudo-distributed mode setting this option to false now.
> I wish to have some option in LocalHBaseCluster for pseudo destr mode where I wish to
>  * separate processes for Master and HRSs
>  * ability to dynamically change HRS number in cluster
>  * managed ZK cluster (like it is in local mode now)
>  * managed small local HDFS cluster
> I think it is very useful for testing, debugging and for user experience with HBase,
who want to try something close to real HBase not some emulation in standalone mode.
