-------------------------------

One last thing, can you make the below work Edward?
{code}
$ echo 'show tables'| src/contrib/hbase/bin/hbase shell 
HBase Shell, 0.0.1 version.

Type 'help;' for usage.

HBase > show tables
    --> Exception in thread "main" java.lang.NullPointerException
        at org.apache.hadoop.hbase.Shell.isEndOfCommand(Shell.java:78)
        at org.apache.hadoop.hbase.Shell.main(Shell.java:55)

>  * Generic Monitoring Function 
>  * A Simplified Import/Export/Migrate Functionality Between different data sources (Hadoop,
HBase) 
>  * A Simplified processing of a logical data model

data across multiple maps in HBase.)
