Description
See this test:
hbase(main):002:0> create 'test', ' cf' hbase(main):003:0> scan 'test' ROW COLUMN+CELL 0 row(s) in 0.1050 seconds hbase(main):004:0> describe 'test' DESCRIPTION ENABLED {NAME => 'test', FAMILIES => [{NAME => ' cf', BLOOMFILTER => 'NONE', REPLICATION_SCOPE => '0', COMPRESSION => 'NO true NE', VERSIONS => '3', TTL => '2147483647', BLOCKSIZE => '65536', IN_MEMORY => 'false', BLOCKCACHE => 'true'}]} 1 row(s) in 0.0540 seconds hbase(main):005:0> put 'test', 'r1', ' cf:1', 'v1' 0 row(s) in 0.0580 seconds hbase(main):006:0> scan 'test', { COLUMNS => [' cf'] } ROW COLUMN+CELL ERROR: Unknown column family! Valid column names: cf Here is some help for this command: Scan a table; pass table name and optionally a dictionary of scanner specifications. Scanner specifications may include one or more of: TIMERANGE, FILTER, LIMIT, STARTROW, STOPROW, TIMESTAMP, MAXLENGTH, or COLUMNS. If no columns are specified, all columns will be scanned. To scan all members of a column family, leave the qualifier empty as in 'col_family:'. Some examples: hbase> scan '.META.' hbase> scan '.META.', {COLUMNS => 'info:regioninfo'} hbase> scan 't1', {COLUMNS => ['c1', 'c2'], LIMIT => 10, STARTROW => 'xyz'} hbase> scan 't1', {FILTER => org.apache.hadoop.hbase.filter.ColumnPaginationFilter.new(1, 0)} hbase> scan 't1', {COLUMNS => 'c1', TIMERANGE => [1303668804, 1303668904]} For experts, there is an additional option -- CACHE_BLOCKS -- which switches block caching for the scanner on (true) or off (false). By default it is enabled. Examples: hbase> scan 't1', {COLUMNS => ['c1', 'c2'], CACHE_BLOCKS => false} 8:57 PM haha 8:58 PM hbase(main):008:0> scan 'test' ROW COLUMN+CELL r1 column= cf:1, timestamp=1308855379447, value=v1 1 row(s) in 0.0450 seconds
We should handle this better.
