scan	hbase> scan 'hbase:meta'   hbase> scan 'hbase:meta', {COLUMNS => 'info:regioninfo'}   hbase> scan 'ns1:t1', {COLUMNS => ['c1', 'c2'], LIMIT => 10, STARTROW => 'xyz'}   hbase> scan 't1', {COLUMNS => ['c1', 'c2'], LIMIT => 10, STARTROW => 'xyz'}   hbase> scan 't1', {COLUMNS => 'c1', TIMERANGE => [1303668804, 1303668904]}   hbase> scan 't1', {REVERSED => true}   hbase> scan 't1', {ALL_METRICS => true}   hbase> scan 't1', {METRICS => ['RPC_RETRIES', 'ROWS_FILTERED']}   hbase> scan 't1', {ROWPREFIXFILTER => 'row2', FILTER => "     (QualifierFilter (>=, 'binary:xyz')) AND (TimestampsFilter ( 123, 456))"}   hbase> scan 't1', {FILTER =>     org.apache.hadoop.hbase.filter.ColumnPaginationFilter.new(1, 0)}   hbase> scan 't1', {CONSISTENCY => 'TIMELINE'} For setting the Operation Attributes    hbase> scan 't1', { COLUMNS => ['c1', 'c2'], ATTRIBUTES => {'mykey' => 'myvalue'}}   hbase> scan 't1', { COLUMNS => ['c1', 'c2'], AUTHORIZATIONS => ['PRIVATE','SECRET']} 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}
count	hbase> count 'ns1:t1'  hbase> count 't1'  hbase> count 't1', INTERVAL => 100000  hbase> count 't1', CACHE => 1000  hbase> count 't1', INTERVAL => 10, CACHE => 1000
