            Reporter: Peter Somogyi

After startup list_regions throw “ERROR: undefined method `toString' for nil:NilClass”.

hbase(main):009:0> list_regions 'ltt'

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']
