ERROR: undefined method `toString' for nil:NilClass
Here is some help for this command:
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']
