HBase Fehler beim Erstellen Tabelle

Question

Ich bin neu in HBase und ich lerne es selbständig. Ich installiere HBase und versuchte, eine Tabelle mit dem folgenden Befehl

hbase(main):008:0> create 'htest', 'cf'

zu schaffen, aber ich bin eine Tonne Fehler ausgelöst. Das ist was kommt:

2016-05-27 02:51:12,835 ERROR [main] client.ConnectionManager$HConnectionImplementation: The node /hbase is not in ZooKeeper. It should have been written by the master.

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:

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', 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.

Ich habe keine Ahnung, was zu tun ist! Jede Hilfe wird geschätzt!

Soll ich auch Zookeeper konfiguriert haben, bevor ich HBase installiert habe? Mein Tutorial hat das nicht gesagt.

Answer 1

Brauchen Sie das HBase-Protokoll für die Fehler zu überprüfen, am häufigsten setzt die Lösung richtige Parameter in der HBase-env.sh-Datei.

Bitte beachten Sie den folgenden Link. Es funktioniert perfekt für mich.
