創建表
我是新來HBase的，並試圖建立與下面的命令hortonworks沙箱殼的HBase表：錯誤在HBase的
create 'testtable', 'colfam1'
這樣做時，我不斷收到此錯誤：
hbase(main):002:0> create 'testtable', 'colfam1'
ERROR: Can't get master address from ZooKeeper; znode data == null
Here is some help for this command:
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',
REGION_REPLICATION => 2, CONFIGURATION => REGION_REPLICATION => 2, 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.
我複製這條線直接從HBase的權威指南，那麼爲什麼不在create聲明的工作？該語法有什麼問題嗎？
不，我沒有在本地安裝，HBase預安裝在虛擬機上，我也沒有集羣，只有一個虛擬設備在我的筆記本電腦上。我找不到start-hbase.sh腳本，還有什麼我應該嘗試的？ – nickshoe
好的。那麼你使用的是Cloudera VM還是Hortonworks？如果您使用的是Cloudera，那麼您應該可以訪問Cloudera Manager，它會告訴您服務的狀態。 – aa8y
不，這是Hortonworks，那麼我應該怎麼做呢？ – nickshoe
