hbase預建分區表,修改壓縮方式
hbase創建region,按照rowkey的劃分來建：
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文件的內容：
0000189005000000000000000000000000000000
0000189010000000000000000000000000000000
0000189015000000000000000000000000000000
0000189020000000000000000000000000000000
0000189025000000000000000000000000000000
0000189030000000000000000000000000000000
0000189035000000000000000000000000000000
0000189040000000000000000000000000000000
0000189045000000000000000000000000000000
0000189050000000000000000000000000000000
0000189055000000000000000000000000000000
下面修改表的壓縮方式：
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
