hbase创建region,按照rowkey的划分来建：

create 'BT_NET_LOG_000','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_001','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_002','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_003','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_004','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_005','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_006','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_007','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_008','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_009','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_010','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_011','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_012','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_013','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_014','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_015','cf',{ SPLITS_FILE => 'splits.txt' }

create 'BT_NET_LOG_016','cf',{ SPLITS_FILE => 'splits.txt' }

splits.txt文件的内容：
0000189005000000000000000000000000000000
0000189010000000000000000000000000000000
0000189015000000000000000000000000000000
0000189020000000000000000000000000000000
0000189025000000000000000000000000000000
0000189030000000000000000000000000000000
0000189035000000000000000000000000000000
0000189040000000000000000000000000000000
0000189045000000000000000000000000000000
0000189050000000000000000000000000000000
0000189055000000000000000000000000000000

下面修改表的压缩方式：
create 'BT_NET_LOG_001','cf',{ SPLITS_FILE => 'split_500.txt' }
disable 'BT_NET_LOG_001'
alter 'BT_NET_LOG_001', NAME => 'cf', COMPRESSION => 'GZ'
enable 'BT_NET_LOG_001'
把GZ改成snappy就可以了
