> ERROR: undefined method `toString' for nil:NilClass
> List all regions for a particular table as an array and also filter them by server name (optional) as prefix
> and maximum locality (optional). By default, it will return all the regions for the table with any locality.
> The command displays server name, region name, start key, end key, size of the region in MB, number of requests
> and the locality. The information can be projected out via an array as third parameter. By default all these information
> is displayed. Possible array values are SERVER_NAME, REGION_NAME, START_KEY, END_KEY, SIZE, REQ and LOCALITY. Values
> are not case sensitive. If you don't want to filter by server name, pass an empty hash / string as shown below.
> Examples:
> hbase> list_regions 'table_name'
> hbase> list_regions 'table_name', 'server_name'
> hbase> list_regions 'table_name', {SERVER_NAME => 'server_name', LOCALITY_THRESHOLD => 0.8}
> hbase> list_regions 'table_name', {SERVER_NAME => 'server_name', LOCALITY_THRESHOLD => 0.8}, ['SERVER_NAME']
> hbase> list_regions 'table_name', {}, ['SERVER_NAME', 'start_key']
> hbase> list_regions 'table_name', '', ['SERVER_NAME', 'start_key']
> Took 0.0283 seconds{noformat}
