　　大家，若是看过我前期的这篇博客的话，则

HBase编程 API入门系列之put（客户端而言）（1）

　　就知道，在这篇博文里，我是在HBase Shell里创建HBase表的。

　　这里，我带领大家，学习更高级的，因为，在开发中，尽量不能去服务器上创建表。

　　所以，在管理端来创建HBase表。采用线程池的方式（也是生产开发里首推的）。

1、最简单的创建HBase表

　　查看，当前已创建有的表

=> ["test_table", "test_table2"]

java api hbase建表指定命名空间 hbase api创建表_shell_04

java api hbase建表指定命名空间 hbase api创建表_shell_05

　　即，创建成功。

hbase(main):057:0> list
TABLE
test_table
test_table2
2 row(s) in 4.1700 seconds

=> ["test_table", "test_table2"]
hbase(main):058:0> list
TABLE
test_table
test_table2
test_table3
3 row(s) in 0.0560 seconds

=> ["test_table", "test_table2", "test_table3"]
hbase(main):059:0> desc 'test_table3'
Table test_table3 is ENABLED
test_table3
COLUMN FAMILIES DESCRIPTION
{NAME => 'f', DATA_BLOCK_ENCODING => 'NONE', BLOOMFILTER => 'ROW', REPLICATION_SCOPE => '0', VERSIONS => '1', COMPRESSION => 'NONE', MIN_VERSIONS => '0', TTL => 'FOREVER', KEEP_DELETED_CELLS

1 row(s) in 1.2370 seconds

2、带最大版本数，创建HBase表

java api hbase建表指定命名空间 hbase api创建表_shell_06

java api hbase建表指定命名空间 hbase api创建表_apache_07
