python hbase 读写

根据hbase的key值范围查询:

for key,data in table.scan(row_start=vin+'_'+str(int(start_t)),row_stop=vin+'_'+str(int(end_t)),revers=False,limit=10000,batch_size=1000);#根据时间戳的范围取值
d = data['cf:point']

hbase读写操作:

import time
import json
import happybase

conn=happybase.Connection(host='',port=9090,timeout=None)
def read_hbase():
    connection=happybase.Connection(host='',port=9090,timeout=None)
    table=connection.table('table_name')
    #row_key='20180727111642_1532661402' #根据key读value
    #info= table.row(row_key)
    #print info
    dic={} #存放到字典里
    for key,value in table.scan():
        dic[key]=value
    print len(dic)
    send_hbase(dic)




def send_hbase(dic):
    table=conn.table('OBD_WIRED_LOC_2018')
    tab=table.batch() #创建batch 
    for key in dic:
        tab.put(key,{'cf:point':json.dumps(dic[key])}) #在字典里取值
    tab.send() #发送
    print 'finish'
read_hbase()
