更新HBase的數據我試圖寫一個函數從保存在HBase的表更新數據。我有一個將被調用,以更新其功能和我有一個很好的開始,但我是在完成它的最後一點點喪失。我可以到其他更新單行基於一個字符串,但比較日誌時候,我似乎無法弄清楚如何做到這一點,因爲沒有設置日誌時間。我將表中的所有值存儲到字典中。這裏是我的代碼:與HappyBase
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
編輯:在我所有的if語句... dict['health']
...是x['health']
?
