> Right now if a shell command gives an error, any error, it then echos the command help.
It makes it harder to see the actual error text and is annoying.
> example:
> {code}
>                                                                                     
                                                                                         
        
> hbase(main):007:0> create 'test:a_table', 'family', { NUMREGIONS => 20, SPLITALGO
=> 'HexStringSplit'}
> ERROR: Unknown namespace test!
> Creates a table. Pass a table name, and a set of column family
> specifications (at least one), and, optionally, table configuration.
> Column specification can be a simple string (name), or a dictionary
> (dictionaries are described below in main help output), necessarily
> including NAME attribute.
> Examples:
> Create a table with namespace=ns1 and table qualifier=t1
>   hbase> create 'ns1:t1', {NAME => 'f1', VERSIONS => 5}
> Create a table with namespace=default and table qualifier=t1
>   hbase> create 't1', {NAME => 'f1'}, {NAME => 'f2'}, {NAME => 'f3'}
>   hbase> # The above in shorthand would be the following:
>   hbase> create 't1', 'f1', 'f2', 'f3'
>   hbase> create 't1', {NAME => 'f1', VERSIONS => 1, TTL => 2592000, BLOCKCACHE
=> true}
>   hbase> create 't1', {NAME => 'f1', CONFIGURATION => {'hbase.hstore.blockingStoreFiles'
=> '10'}}
>   hbase> create 't1', {NAME => 'f1', IS_MOB => true, MOB_THRESHOLD => 1000000,
MOB_COMPACT_PARTITION_POLICY => 'weekly'}
> Table configuration options can be put at the end.
> Examples:
>   hbase> create 'ns1:t1', 'f1', SPLITS => ['10', '20', '30', '40']
>   hbase> create 't1', 'f1', SPLITS => ['10', '20', '30', '40']
>   hbase> create 't1', 'f1', SPLITS_FILE => 'splits.txt', OWNER => 'johndoe'
>   hbase> create 't1', {NAME => 'f1', VERSIONS => 5}, METADATA => { 'mykey'
=> 'myvalue' }
>   hbase> # Optionally pre-split the table into NUMREGIONS, using
>   hbase> # SPLITALGO ("HexStringSplit", "UniformSplit" or classname)
>   hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO => 'HexStringSplit'}
>   hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO => 'HexStringSplit',
REGION_REPLICATION => 2, CONFIGURATION => {'hbase.hregion.scan.loadColumnFamiliesOnDemand'
=> 'true'}}
>   hbase> create 't1', {NAME => 'f1', DFS_REPLICATION => 1}
> You can also keep around a reference to the created table:
>   hbase> t1 = create 't1', 'f1'
> Which gives you a reference to the table named 't1', on which you can then
> call methods.

> hbase(main):008:0> create_namespace 'test'
> Took 0.2554 seconds                                                                 
                                                                                         
                             
> hbase(main):009:0> create 'test:a_table', 'family', { NUMREGIONS => 20, SPLITALGO
=> 'HexStringSplit'}
> Created table test:a_table
> Took 1.2264 seconds                     
> {code}
> I was trying to make a table in the test namespace before making the namespace. Much
faster to recognize and move on when the error text isn't followed by 80x the text.
