Example: hbase> scan 't1', {RAW => true, VERSIONS => 10}Besides the default 'toStringBinary' format, 'scan' supports custom formattingby column. A user can define a FORMATTER by adding it to the column name inthe scan specification. The FORMATTER can be stipulated: 1. either as a org.apache.hadoop.hbase.util.Bytes method name (e.g, toInt, toString) 2. or as a custom class followed by method name: e.g. 'c(MyFormatterClass).format'.Example formatting cf:qualifier1 and cf:qualifier2 both as Integers: hbase> scan 't1', {COLUMNS => ['cf:qualifier1:toInt', 'cf:qualifier2:c(org.apache.hadoop.hbase.util.Bytes).toInt'] } Note that you can specify a FORMATTER by column only (cf:qualifer). You cannotspecify a FORMATTER for all columns of a column family.Scan can also be used directly from a table, by first getting a reference to atable, like such: hbase> t = get_table 't' hbase> t.scanNote in the above situation, you can still provide all the filtering, columns,options, etc as described above.hbase(main):018:0> scan 'scores'ROW COLUMN+CELL Jerry column=course:art, timestamp=1467043674178, value=80 Jerry column=course:math, timestamp=1467043661806, value=100 Jerry column=grade:, timestamp=1467043649929, value=2 Tom column=course:art, timestamp=1467043633328, value=97 Tom column=course:math, timestamp=1467043619083, value=87 Tom column=grade:, timestamp=1467043589481, value=1 2 row(s) in 0.0640 secondshbase(main):019:0> get 'scores', 'Tom'COLUMN CELL course:art timestamp=1467043633328, value=97 course:math timestamp=1467043619083, value=87 grade: timestamp=1467043589481, value=1 3 row(s) in 0.0310 secondshbase(main):020:0> create 'scores', 'grade', 'course'ERROR: Table already exists: scores!Here is some help for this command:Creates a table. Pass a table name, and a set of column familyspecifications (at least one), and, optionally, table configuration.Column specification can be a simple string (name), or a dictionary(dictionaries are described below in main help output), necessarily including NAME attribute. Examples:Create a table with namespace=ns1 and table qualifier=t1 hbase> create 'ns1:t1', {NAME => 'f1', VERSIONS => 5}Create a table with namespace=default and table qualifier=t1 hbase> create 't1', {NAME => 'f1'}, {NAME => 'f2'}, {NAME => 'f3'} hbase> # The above in shorthand would be the following: hbase> create 't1', 'f1', 'f2', 'f3' hbase> create 't1', {NAME => 'f1', VERSIONS => 1, TTL => 2592000, BLOCKCACHE => true} hbase> create 't1', {NAME => 'f1', CONFIGURATION => {'hbase.hstore.blockingStoreFiles' => '10'}} Table configuration options can be put at the end.Examples: hbase> create 'ns1:t1', 'f1', SPLITS => ['10', '20', '30', '40'] hbase> create 't1', 'f1', SPLITS => ['10', '20', '30', '40'] hbase> create 't1', 'f1', SPLITS_FILE => 'splits.txt', OWNER => 'johndoe' hbase> create 't1', {NAME => 'f1', VERSIONS => 5}, METADATA => { 'mykey' => 'myvalue' } hbase> # Optionally pre-split the table into NUMREGIONS, using hbase> # SPLITALGO ("HexStringSplit", "UniformSplit" or classname) hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO => 'HexStringSplit'} hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO => 'HexStringSplit', CONFIGURATION => {'hbase.hregion.scan.loadColumnFamiliesOnDemand' => 'true'}} hbase> create 't1', {NAME => 'f1', DFS_REPLICATION => 1}You can also keep around a reference to the created table: hbase> t1 = create 't1', 'f1'Which gives you a reference to the table named 't1', on which you can thencall methods.hbase(main):021:0> version0.98.20-hadoop2, r9624f3a9eb76f84656a41de0e2099c97f949e831, Tue Jun 7 17:40:20 PDT
