1、安装完hbase之后，进入shell报错

hbase(main):002:0> create 'test', 'cf1'
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'}

2、看不出什么问题，java的报错给的信息太少，只能看log日志了

日志中一直不断的出现等待region server，感觉好像是hmaster和regionserver无法连接
3、查看hbase-site.xml的配置信息

<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>

把上面这部分信息去掉
4、重启hbase
5、再次进入shell中创建表

grid@master1:/usr/local/hbase/conf$ start-hbase.sh
starting master, logging to /usr/local/hbase/logs/hbase-grid-master-master1.out
slave3: starting regionserver, logging to /usr/local/hbase/bin/../logs/hbase-grid-regionserver-slave3.out
