- ERROR: org.apache.hadoop.hbase.PleaseHoldException: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing
- Here is some help for this command:
- Create table; pass table name, a dictionary of specifications per
- column family, and optionally a dictionary of table configuration.
- Dictionaries are described below in the GENERAL NOTES section.
- 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', 'f1', {SPLITS => ['10', '20', '30', '40']}
- hbase> create 't1', 'f1', {SPLITS_FILE => 'splits.txt'}
- hbase> # Optionally pre-split the table into NUMREGIONS, using
- hbase> # SPLITALGO ("HexStringSplit", "UniformSplit" or classname)
- hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO => 'HexStringSplit'}

查看 master:60010 发现hbase.rootdir 没有使用HDFS，典型的配置错误啊~~

hbase.rootdir 参数写成了 hbase.root.dir
hbase-site.xml如下：
- <configuration>
- <property>
- <name><span style="color: rgb(255, 0, 0);">hbase.root.dir</span></name>
- <value>hdfs://master:9000/hbase</value>
- </property>
- <property>
- <name>hbase.cluster.distributed</name>
- <value>true</value>
- </property>
- <property>
- <name>hbase.master</name>
- <value>hdfs://master:<span style="color: rgb(255, 0, 0);">6000</span></value>
- </property>
- <property>
- <name>hbase.zookeeper.quorum</name>
- <value>master,slave1,slave2</value>
- </property>
- </configuration>
修改hbase-site.xml后，重启集群，一切恢复正常。
