我试图编写一个函数来更新HBase中保存的表中的数据。我有一个函数,将被调用来更新它,我有一个很好的开始,但我有一点迷失在结束它。我可以将基于一个字符串的单个行更新到另一个字符串,但是在比较日志时间时,我似乎不知道如何做到这一点,因为没有设置日志时间。我正在将表中的所有值存储到字典中。这是我的代码:
def updateHBase(row):
dict = row.asDict() #create a dictionary from Row
columns = dict.keys()
for col in columns: #creates the colfamily:colname for happybase format
dict["DriveInfo:" +col] = dict.pop(col) #adds data into rows
del dict[DriveInfo:serialnumb] #removes the row key that HBase uses, serialnum
x = table.row(row.serialnum)
if (len(x) == 0) #length of row is zero, row key does not exist
table.put(row.serialnum, dict) #add new row is row key does not exist
else #check for health
if (dict['health'].lower() != 'healthy') #if the row isnt healthy... next steps
if (dict['health'].lower() != 'archived' and x['health'] == 'archived' and dict['logtime'] < x['logtime']) #update a row with a health status of archived
table.put(row.serialnum, dict)
else #if the row that is being replaced isn't archived, just replace the row
table.put(row.serialnum, dict)
return
elif (dict['logtime'] > x['logtime'] and dict['health'].lower() == 'healthy') # new log time > old log time and health is healthy, replace the row with new data
table.put(row.serialnum, dict)
else
return
编辑:在我所有的if语句中应该。。。dict['health']
。。。是x['health']
?在
明白了。。。在
