stack commented on HBASE-10389: ------------------------------- +1 for 0.96. > Add namespace help info in table related shell commands > ------------------------------------------------------- > > Key: HBASE-10389 > URL: https://issues.apache.org/jira/browse/HBASE-10389 > Project: HBase > Issue Type: Improvement > Components: shell > Affects Versions: 0.96.0, 0.96.1 > Reporter: Jerry He > Assignee: Jerry He > Attachments: HBASE-10389-trunk.patch > > > Currently in the help info of table related shell command, we don't mention > or give namespace as part of the table name. > For example, to create table: > {code} > hbase(main):001:0> help 'create' > Creates a table. Pass a table name, and a set of column family > specifications (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: > hbase> create 't1', {NAME => 'f1', VERSIONS => 5} > 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 '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'}} > 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 then > call methods. > {code} > We should document the usage of namespace in these commands. > For example: > #namespace=foo and table qualifier=bar > create 'foo:bar', 'fam' > #namespace=default and table qualifier=bar > create 'bar', 'fam' -- This message was sent by Atlassian JIRA (v6.1.5#6160)
